What is a IP ?
IP – (Internet Protocol Address) Unique number to represent every computer in a network. All the computers on the Internet have a unique IP address. To the Internet, a specific server’s IP address is all numbers and dots in the format 000.000.000.0. Humans are not as good as computers at remembering numbers so IP numeric addresses also have a textual representation. The usual format is: [machine name].[sponsoring organization].[type of organization]
An Internet Protocol address (IP address) is a logical numeric address that is assigned to every single computer, printer, switch, router or any other device that is part of a TCP/IP-based network.
The Internet Protocol Address is the core component on which the networking architecture is built; no network exists without it. An Internet Protocol Address is a logical address that is used to uniquely identify every node in the network. Because Internet Protocol Address are logical, they can change. They are similar to addresses in a town or city because the Internet Protocol Address gives the network node an address so that it can communicate with other nodes or networks, just like mail is sent to friends and relatives.
The numerals in Internet Protocol Address are divided into 2 parts:
- The network part specifies which networks this address belongs to and
- The host part further pinpoints the exact location
Pay2Amigos explains Internet Protocol Address (IP Address)
An Internet Protocol Address is the most significant and important component in the networking phenomena that binds the World Wide Web together. The Internet Protocol Address is a numeric address assigned to every unique instance that is connected to any computer communication network using the TCP/IP communication protocols.
Network nodes are assigned Internet Protocol Address by the Dynamic Host Configuration Protocol server as soon as the nodes connect to a network. DHCP assigns Internet Protocol Address using a pool of available addresses which are part of the whole addressing scheme. Though DHCP only provides addresses that are not static, many machines reserve static Internet Protocol Address that are assigned to that entity forever and cannot be used again.
IP addresses falls into two types:
- Classfull IP addressing is a legacy scheme which divides the whole IP address pools into 5 distinct classes—A, B, C, D and E.
- Classless IP addressing has an arbitrary length of the prefixes.
