What is an IP address?
The Internet Protocol (IP) is a protocol used for delivering data packets, known as 'datagrams' or 'packets' across a network using the Internet Protocol Suite (TCP/IP). The long standing Internet Protocol Version 4 (IPv4) is still the dominant addressing protocol of the Internet, although the new Internet Protocol Version 6 (IPv6) is being deployed worldwide. IPv4 uses 32-bit (four-byte) addresses, which limits the address space to 4,294,967,296 possible unique addresses however these are fast running out and the new IPv6 will allow 128-bit addresses. IPv4 addresses are normally written in dot-decimal notation, which consists of the four octets of the address expressed in decimal and separated by periods. An example of such an address is '62.172.189.189'. To connect to the internet you modem/router needs to have an IP address which is allocated by one of two methods:

• Dynamically Allocated IP - Each time you make a connection to the internet your service provider allocates your computer with a temporary IP address at random from it's pool.
• Fixed (static) IP - The provider allocates from it's pool a permanent IP address to your system which you retain for the duration of your account with that provider.
