“Find Host IP” and Other Jargon Deciphered

Find host IP addresses with sites like ipaddressreport.com

Ideally, you’d never need to know most of the jargon that describes the inner workings of the Internet. Sadly, however, we don’t live in an ideal world and the Internet is not a magical utopian realm. The fact that most people think the Internet is magical is a testament to the quality of the technology that allows people to use it without understanding it. However, if you’re running your own site or trying to take advantage of advanced applications, you can and will encounter problems and you’ll need to do some basic troubleshooting. At some point you’re likely going to encounter a manual where the next step is written as, “find host IP.” This is a fairly simple task and the terminology involved refers to the basic building blocks of the Internet, but there is no shame in finding these concepts confusing.

The good news is that, despite what the technological masterminds may want you to believe, you don’t actually have to be a wizard to understand the nuts and bolts of the Internet. The first hurdle you’re going to encounter is the need to come to terms with the specialized language that allows you to find and understand the information you need to accomplish your goals. The biggest problem in understanding the jargon is the fact that you’ll encounter the same words and abbreviations in different contexts and they’ll imply different things. For example, you’ve probably seen the abbreviation “IP” many times. You might even know it stands for Internet Protocol: a standardized system used for getting information to the right place on an interconnected network. You’ve probably also seen it used many times as a shorthand for “Internet Protocol address,” as in the instruction, “Find Host IP.” In this case, rather than talking about Internet Protocol in general, what is being referred to is the specific address, the identifying number assigned to a device so that it can be accessed through a network.

Any definition will tell you that that an IP address is a unique number assigned to a given device, and this is technically correct, but it’s not quite that simple. An IP address is a series of four numbers, each separated by a decimal and each consisting of up to three digits (For example: 156.189.248.158). Each decimal-spaced value can be from 0 to 255, which means there are something like 4.3 billion possible combinations and every entity connected to the Internet at any given time will have one of these different addresses assigned to it into order to make it differentiable and accessible.

However, most people connect to the Internet using a modem and, if you have more than one computer using a given Internet connection, you’ll probably be using a router. Effectively, this means you’re operating a LAN (Local Area Network) in order to allow multiple computers to share one resource (in this case the Internet connection). When communicating internally, a router will probably be accessed using an IP address like 192.168.1.1 when being access by a computer (like your computer) on the LAN. Each computer on this network will have an address subordinate the router’s IP address (like 192.168.1.167) to identify it on the network and these numbers might be the same for different people on different networks. This creates no conflict because these IP addresses are used only on the local area network, not the public Internet. The router acts as a gateway to the outside world beyond the local area network. When communicating externally (across the Internet), it will use an IP address assigned by your Internet service provider to make communication possible.

The reason for all this detail is that the instruction, “find host IP” will mean different things depending on the task. If you’ve encountered a problem on your LAN you may need to find the IP address of machines so you can make sure your network is configured without any conflicts and that any incoming information is forwarded to the computer. In this case the “host” whose IP address you’re trying to identify is a machine on your network. If it refers to the machine you are actually using to run a given piece of software, you might see the term “Local Host.” As noted above, on any given LAN you’re likely to see similar or even identical IP address numbers as other LANs and this isn’t a problem.

There are, however, many other reasons you might want to find a “host IP,” and this won’t always refer to a limited number of machines in your home or office. A “host,” simply put, is any machine that stores data or operates a piece of software. When accessing different pages on the Internet, you’ll access many different hosts. Generally speaking, when communicating with hosts over the Internet we use Domain Names rather than IP addresses because words are easier to remember. This is made possible by Domain Name System (DNS) servers which provide indexes that translate domain names, like www.goodhost.org, into the relevant IP address. Sometimes these systems fail or become out of date, and one good way to troubleshoot for such issues to access a host by IP address rather than its name.

There are many other reasons why you’d want to find IP addresses and, fortunately, many resources that can help you with diagnostic tasks. You can type “ipconfig” into a command line on your PC to get information about your LAN. To find your IP address or that of other hosts on the Internet you can try sites like ipaddressreport.com. Hopefully, just having a basic understanding about how the Internet is navigated and held together will help you get started.
