An "IP address" is a numeric identifier for a device connected to a LAN or to the internet (which is sometimes called a "WAN". It is more or less "the" WAN.)

IP addresss consist of 4 or 6 numbers separated by "decimal" points. is a common IP address for the router at the heart of a LAN that is connected to the internet.

The four (or six) numbers in the IP address are usually written in decimal. Sometimes they are written in hex. (If you see any letters in the IP address, it is written in hex.) They are always in the range 0-255 inclusive. I.e. they will always be zero or more, but never more than 255. (Those are the numbers you can show with eight 1's and 0's in a binary code. Such numbers are called "bytes", which derived from "by eight", which was how such numbers were described in the early days. Eight 1's and 0's, get it?) and FF.FF.FF.00 are the same thing, written differently. (Just like 12, twelve, "a dozen", 0x1100 and $C all are the same thing, written differently... when you know the conventions. (The last two are the number in binary and hex, respectively.)

Leading zeros are usually optional... might be written by a pedantic person, or for a badly written interface... but usually is acceptable.

When an IP address is written in hex, when a letter is used, the case doesn't matter. $a and $A both mean what we usually call "ten".

See also "IP address".

(What does "IP" stand for? "Internet Protocol".)

Hope that helped?

I hope that was helpful. Getting started is always so tedious. This page is just a "glossary entry" off of my main "Getting started with Raspberry Pi" page.

Why does this page cause a script to run? Because of the Google panels, the code for the search button, etc. Why do I mention scripts? Be sure you know all you need to about spyware.
