IP Addresses Finding, Recognizing and Using
IP addresses are like real-world addresses, they are identifiers for devices or computers connected to TCP/IP networks. The entire TCP/IP networking protocol is based on the concept of a unique IP address for every object linked to the network. ipv6 proxies
IP addresses have a fairly simple format. They're made of four octets (8 bits), separated by periods. An octet can be from 0-255 (the first octet cannot be 0), with the exception of some'booked' patterns (127.0.0.1 should always resolve to the local machine).
Private networks, for example outside LANs can have some IP addresses they need provided that each is special, however, to link into the public and controlled Internet, you'll have to use a registered IP address (dispersed by the various Internet registries: ARIN, RIPE, etc..)
The number of available addresses in an IPv4 setup is slightly over 4,000,000,000, nevertheless, around 20,000,000 are reserved for particular uses such as personal networks. As more and more users and items (together with all the VoIP revolution, as well as kitchens and automobiles becoming increasingly more connective, this issue will become more acute ) we are rapidly closing in on the most number of IP addresses available. Thus, IPv6 was invented.
IPv6 uses considerably longer addresses: being 128 bits wide, IPv6 addresses can have 2128 different addresses, or based on Wikipedia:"When the earth were made entirely out of 1 cubic millimeter grains of sand, and then you could give a unique address to each grain in 300 million planets the size of the planet." go to website
On to actually finding your IP address... there are various ways to do it, and each can be"wrong" for the true IP address you're looking for. A lot of people do not connect directly to the Internet, some undergo corporate proxies, some undergo server supplier"compressing" or even caching proxies, and many use proxies for other reasons. This makes finding an IP address considerably more difficult than one would expect.
