What Is An IP Address?

An IP Address is a unique string of numbers separated by periods that identifies each computer and/or network enabled device that uses the Internet Protocol to communicate with one another.  There are two types of IP Addresses: IPv4 & IPv6.

IPv4 has been around for a long time and is the most visible one.  It is 32 binary digit long but since it human mind are not trained to deal with such a long number, IP Address is converted to 4 decimal numbers of 8 bits (binary digit) and each is separated by a dot.  For this reason, IP is often referred to as having a Quad-Dot notation.  When you hear of the term Quad-Dot, don't take it for 4 dots but it's rather 4 numbers, each separated by a dot.

IPv6 is the latest version that is supposed to be replacing IPv4 since we have exhausted IPv4.  IPv6 is 128 bits long so the pool of available IP addresses is much more bigger compared to IPv4.  If we were to use the "dot" notation to represent an IPv6 address we would have 16 decimal numbers separated by dots - this would be too long of a number to deal with so the International Engineering Task Force (IETF) converted 128 binary digit number to a string of Hexadecimal numbers of 16 bits each.  And to differentiate IPv6 from IPv4 representation, they use a semicolon instead of a dot.  Another reason to go with the semicolon is the IPv6 Mapped Address.

Why does geo location shows my IP address in the one location when I am at another location?

When an organization requests a block of IP address, along with the justification for the request they also send in the business contact, technical contact and the address (among other things) of the organization requesting the IP address block.  This is the data recorded for Geo Location service.  Most organization breaks up this block of IP addresses and uses them at multiple physical locations and never bother to update the geo location therefore you could see the administrative record address instead of the location where the IP addresses are used.

This tends to happen to large corporations with multiple sites and large infrastructures.  The only way to correct this is with assistance from users like you.  You can help by sending in corrections so we can update geo location data to reflect the correct locations.

Why does geo location shows my Zip Code off by a few digits?

When you subscribe to a broadband connection, broadband internet service provider (like AT&T, Comcast, Cox...) records your address, cross references it with geo location database and updates this geo data automatically.  Most broadband connections are assigned dynamic IP addresses which means the IP address can change whenever you reset your broadband router and as the result, the IP address you use now could have been used at another address or zipcode within a small geographical area.  If the geo data isn't updated in time you will see the old geo location data resulting in the zipcode to be off by a few digits.

This typically happens to residential broadband subscribers as most business subscribers have static IP addresses allocated to them.
