Your IP address usually links you to an Internet Service Provider (ISP), and that often links you to a particular geographical location, or to a particular company. Internet tools such as WHOIS and Reverse DNS lookups may identify you, your employer or school, or computers that use your address, including mail or web servers.
Before claiming an IP address, the client should probe the newly received address (e.g. with ARP), in order to find if there is another host present in the network with the proposed IP address. [ 8 ] : sec. 2.2 If there is no reply, this address does not conflict with that of another host, so it is free to be used.
The simplest type of NAT provides a one-to-one translation of IP addresses (RFC 1631). RFC 2663 refers to this type of NAT as basic NAT, also called a one-to-one NAT. In this type of NAT, only the IP addresses, IP header checksum, and any higher-level checksums that include the IP address are changed. Basic NAT can be used to interconnect two ...
A Canonical Name (CNAME) record is a type of resource record in the Domain Name System (DNS) that maps one domain name (an alias) to another (the canonical name). [1]This can prove convenient when running multiple services (like an FTP server and a web server, each running on different ports) from a single IP address.
RFC 791 describes the procedure for IP fragmentation, and transmission and reassembly of IP packets. [1] RFC 815 describes a simplified reassembly algorithm. [2] The Identification field along with the foreign and local internet address and the protocol ID, and Fragment offset field along with Don't Fragment and More Fragments flags in the IP header are used for fragmentation and reassembly of ...
IP addresses, however, may be controlled by 12 different people in one year, or hundreds of different people in one day. This is because the IP address isn't a human, it is simply a routing address, similar in some ways to your phone number. Unlike a phone number, most IP addresses aren't assigned to individual humans, but on an "as needed" basis.
