All About IP Addresses

Every machine on the Internet­ has a unique identifying number, called an IP Address. A typical IP address looks like this:

216.27.61.137

The four numbers in an IP address are called octets, because they each have eight positions when viewed in binary form. If you add all the positions together, you get 32, which is why IP addresses are considered 32-bit numbers. Since each of the eight positions can have two different states (1 or 0) the total number of possible combinations per octet is 28 or 256. So each octet can contain any value between 0 and 255. Combine the four octets and you get 232 or a possible 4,294,967,296 unique values!

Out of the almost 4.3 billion possible combinations, certain values are restricted from use as typical IP addresses. For example, the IP address 0.0.0.0 is reserved for the default network and the address 255.255.255.255

      In regards to IP addresses for many years IPv4 was standered now they are starting to roll out the IPv6 and their are two other terms that go with IP addresses public IP that when people are clecting stats they see. Privite IP is when your routor brakes it down to you our your computer it is your privite IP address. Another thing about IP Addresses public are great for web stats but the other one can give out information that should not be public. If you need to see reset an IP address due to ip address conflict, run cmd and type: ip release than ip renew. This will get another ip from your router.
