Would a few of the website hosting gurus here please explain briefly exactly what the numbers (between your us dot separators) within an Ip signify...

for example: IP XXX.XXX.XXX.XXX

I am quite a new comer to all of this... but actually want to learn fast. Looked everywhere, but could not discover the solution yet :O(
An Ip routes a request to some specific server, every site is going to be connected with one whether unique or shared.

There's no importance with what number you receive. Is the house better since it is number 54 and your's is 200? No.

Lacking nipping up a magazine on networking necessities, you might like to have a look at Daryl's TCP/IP Primer at http://ipprimer.windsorcs.com/, particularly section 6 for any brief summary of IP classes.

Oops... why talk sarcastic?

All I requested was the logic behind the amounts within the Ip... just like the number inside a zipcode of the regular house address has some logic behind it.

I needed to be aware what each group of amounts within the Ip realistically known to, that's all
Student,

You can keep your education by searching for what sarcasm is, since it does not come in what Admin stated. The purpose was that there is no significance with what amounts one may have to have an Ip.

For example, 65.65.100.122 isn't any better by any means than 240.212.199.066, they all are just amounts.

Though I possibly could be mistaken, In my opinion the final group of four amounts may visit the same Web service provider (ncluding hosts), a minimum of area of the time. Quite simply, say an Web service provider comes with an Ip of 240.212.199.xxx, they might possess the entire selection of the final four amounts, from 001 to 255.

For several functions, including obstructing access and RBL (Realtime Black List), it causes it to be easy to block a whole selection of addresses with just the first three teams of 4 in keeping.

Duster: Student, was estimating Admin.

The ip that you will get is dependent around the nettwork architecture of the web service provider, and just how they as well as their provider(s) choose to break them up.
Remember about network masks, etc. I'll detail it after i return..... inside a hurry to leave the doorway, sorry.....
The IP addresses are simply amounts. There actually is no importance to the a bouquet of them. (Incidentally, each one of the three digit amounts between your dots, are known as Octets.)

What happens if you hear people discuss how someone's IP is incorporated in the same block as some company. Which means that company has asked for, and it has had designated, a block of IP addresses. They've reserved them, for a moment, for his or her own use, meaning nobody else may use them. In otherwords, that individual is in some manner associated with that company.

You will find different Classes of IP Addresses, A, B, and C. These Courses are based on the Mask that's combined with the Ip. In my opinion most IP addresses used on the web are generally Class B or Class C. The Category designation does not mean one works more effectively compared to other, precisely how the network equipment translates the address.

It's only several, and it has no physical relationship.

Hope this really is useful info.

Ok, here's what I recall from my Bay Systems class.

An IP includes 4 octets, each with a variety of to 255 (though and 255 aren't typically used). The very first octet determines what class of IP has been used. I do not remember all of the ranges, however i remember that - 128 is really a class A. You will find 4 different classes, A,B,C,D. Additionally to IP's additionally you may have a subnet mask. A subnet mask enables one IP for use by multiple machines (pretty much). A subnet mask typically is one thing like 255.255.. though other amounts might be used.

If you have 10 computer systems on the network and just get one IP designated for you. Using subnet hiding, you should use that certain address to gain access to all 10 machines.

IP's are utilized to identify a specific device on the given network, this is often a printer, PC, scanner, server or any other device. Typically IP's are bound (linked) to MAC address's making use of your computer systems OS. A MAC address is really a hard coded address within the NIC (network interface card). Each NIC (theoretically) has it's own unique MAC address (designated in the factory).

On the different subject if you've ever heard about DHCP and wondered what it really maybe it was means Dynamic Host Control Protocol. This can be a way where you'll have a pool of IP amounts, say 128.1.4.100 to 128.1.4.200, and rather than setting a seperate Ip for every machine, the device asks the DHCP server for any temp IP. The server then assigns the following available IP towards the machine requesting it. When that machine is performed utilizing it (say switched off) then that IP is defined into the pool of amounts for another person to make use of. This really is typically how dial-up connections work. You dial in and also the port you dial in on demands an IP in the DHCP server and also you utilize it until you hang up the phone, then time is launched into the pool.

Well, hope this assisted. TCP/IP is an extremely complex protocol to know. You will find a number of different books and classes about them. If I am not mistaken there's a whole test devoted to TCP/IP for that MSCE.

More details (plus some minor corrections):

DHCP=Dynamic Host Configuration Protocol, but otherwise it really works much like Mike stated. You receive a "lease" with an Ip, for use for the current session, which lease is usually for a short while for such things as dial-up connections. For those who have an always-on connection, for example DSL or perhaps a cable modem, the lease is usually longer - and when the body and connection is constantly up and you are watching in the proper time, you may really begin to see the system trying to resume the lease around the Ip it's (or, obviously, the mistake stating that the machine cannot renew the lease). On LANs which use DHCP, static products for example ink jet printers and servers will often have an designated IP, while user work stations use DHCP.

Subnet masks aren't always necessary, but generally, they inform your system where you can search for other computer systems around the network. For example, in case your subnet mask is 255.255.., the very first two octets of the IP let you know what network you are on, and also the latter let you know what host you're - therefore if your Ip was 208.167.138.10, presuming the subnet was setup correctly on the customer and network level (router), theoretically you need to have the ability to speak with any machine around the 208.167 network without using a gateway. You are able to further split subnets, consider many people fall under Class C ranges (using subnet mask 255.255.255.) it is not practical (or possible, given some ranges).

The upper and lower finishes of the range (xxx.xxx.xxx. and .255) are often restricted to showing the entire subnet (.), or broadcast traffic (.255). Another for example: IIS under NT enables to to grant or deny access according to IP ranges. To permit or deny them, one enters them as xxx.xxx.xxx., which provides coverage for the whole subnet.

If you are really thinking about learning these items (why is this so? ), you might like to get virtually the exam prep books for Networking Necessities or TCP/IP. The very first provides you with some fundamental info on the different methods, including TCP/IP, and really should also give some decent info on the OSI model. The 2nd should help if you want to obtain lower in to the guts of things.

Or help you to get to rest if you are an insomniac.

Sorry basically seem sarcastic, I'd no aim of being rude. Please accept my apology.

There's no significance within the IP you receive.

Although will discover some good examples like 208.xxx.xxx.xxx are mainly located in america and whatever.xxx.xxx.xxx are united kingdom based etc... but theoretically In my opinion any IP number could be for just about any server all over the world. Some companies/organizations reserve blocks of Insolvency practitioners for several use.

Sorry basically seem sarcastic, I'd no aim of being rude. Please accept my apology.
Admin... and i apologize for thinking you will probably have been !!!

WOW !!! i had been the initial user of the forum after i published this. and that i have a larger answer than i was expecting.

Everyone are merely great !!!!

Thanks. I believe i'll lookup the recommended links and educate yourself about this to understand more.

On the closing note, i've got a strong stomach feel (it is simply a stomach feeling!!) these amounts might have some logical significance... because amounts generally do !!!

Maybe there's not that much physical significance possibly... that's why i'd given my original question the title "ip address p-MYSTIFIED"!!

Only i wasn't planning on be this large a mysterious !! however, you web gurus put a great deal of light about them.

Thanks once more !!

what goes on when all of the possible mixtures of xxx.xxx.xxx.xxx or how ever it really works are adopted ? Will the web be full ?

Sorry Iam fairly stupid only at that. However , I must learn more. Due to the fact next time the cable tech is available in here to repair something..I'll have the ability to understand his jargon... incidentally .. exactly what does a gateway do ?
Presently, you will find Large Plans for IP6. Believe me, don't be concerned concerning the amounts drying out up. The entire discussion turning around it's crashingly dull for those who don't particularly desire to be network nerds/cowboys.

A gateway is a bit of network equipment that enables your personal computer on a single subnet to speak to your personal computer on another subnet. It may determine, in the address from the recipient, if your packet of knowledge ought to be shuttled across towards the other net or sent along around the current one, and usually offers translation service between methods.

Like a for example, if you have an e-mail account together with your Web service provider, and also the mail server is actually on a single subnet as the pc (that's, you have been designated an Ip on a single net because the Ip from the mail server). Whenever you create a request to that particular server, the request doesn't have to visit outdoors the subnet that you're on - so, you shouldn't have for any gateway, as every request that you simply make towards the email server is going to be around the immediate net. However, when you begin asking for webpages from outdoors your personal subnet, your Web service provider includes a gateway that handles individuals demands, properly routing the request (and also the packets you get in reaction for your request) towards the proper destination. This is the quite simple version of the items happens, without adding hubs, bridges, etc. As recommended formerly, worthwhile study guide for Networking Necessities or TCP/IP will break it lower more fully, supplying info on the hardware i did so something more important, in addition to wearing down the methods (TCP/IP, that is technically a suite, or IPX, etc.) to their various layers and processes.

If you're really thinking about TCP/IP, look at your college or local college. They frequently offer classes about this kind of factor. My home, the city college really provides a course on 'cisco' Router certification.

Escape! That's pretty awesome! I simply lately discovered exactly what the neighborhood College needed to offer. Good quality stuff!

Within Cali, college is fairly cheap (have a pity party for that relaxation individuals), with classes costing $14/unit (an ordinary 3 unit class costs $45). Can't beat by using a defunct monkey.
Chicken,

I am envious.

Most college courses on computer systems cost at *least* $300 right here, and when I truly desired to learn TCP/IP I must see Microsoft or among the other training companies (that amounted to on the grand)
Nukem, they estimate that it'll "run out" of IP's from 2 - two decades. They never appear to agree from the number. Anyway, as Anette mention for this reason IPv6 is on it's way a alternative for that current system.

More discussions about IP's are available at http://www.scriptkeeper.com/ubb/Forum5/HTML/001041.html # just disregard the "fights"... hehe
