What is an IP address
What is an IP address? simply put an IP address (Internet Protocol) is a number assigned to each and every computer on the internet, it is an address a number for your computer that identifies and sends traffic flow (data packets) from computer to computer, each computer will have it’s own Internet Protocol a number or IP address.
That’s the end of the simple part, an IP address a number, the rest you may not want to read, we will endeavor to summarise the principles in simple terms, but if you need an in depth study, and have a lot of time on your hands, Wikipedia has most of the IP answers, scope and some depth of authority.
Most computers will have dynamic IP addresses, numerical IPv4 = 32 decimal (base-10) 4 groups of 4, = (132.89.673.87) TheIP V4 is the dominant Internet Protocol in the Internet Layer in use today is IPv4; the number 4 is the protocol version number carried in every IP datagram. IPv4 is described in RFC 791 (1981).

The successor to IPv4, is the IPv6, the most prominent modification over version v4 is the addressing system, IPv6 uses 128-bit addresses (c. 340 undecillion, or 3.4×1038 addresses) – a binary IPv6 = 128 bits – 8 groups of 4, hexadecimal (base-16) = (2001:cdba:0000:0000:0000:0000:3257:9652).
Although adoption of IPv6 has been slow, as of June 2008, all United States government have basic support for the system at backbone level.
