IP Addresses

Every Computer that is connected to internet has unique IPAddress.

It is 32 bit number.

Two types of IP Address.

Static IP Remain Same at every session

Dynamic IP Changed at Every Session.

IP Addresses

IANA manages global IP ranges space.

IANA works in cooperation with five Regional Internet Registries(RIRs) to allocate IP address blocks to Local Internet Registries

(Internet service providers) and other entities.

IP Addresses

There are currently five RIRs in operation:

American Registry for Internet Numbers (ARIN) for North America and parts of the Caribbean.

RIPE Network Coordination Centre (RIPE NCC) for Europe, the Middle East and Central Asia.

Asia-Pacific Network Information Centre (APNIC) for Asia and the Pacific region.

Latin American and Caribbean Internet Addresses Registry (LACNIC) for Latin America and parts of the

Caribbean region.

African Network Information Centre (AfriNIC) for Africa

IPV4

IPv4

Internet Protocol version 4 (IPv4) is the fourth revision in the

development of the Internet Protocol (IP) and it is the first version of

the protocol to be widely deployed.

to 4,294,967,296 (232) possible unique addresses.

IPV6

IPv6

Internet Protocol version 6 (IPv6) is the next-generation Internet

Layer protocol for packet-switched internet works and the Internet

IPv6 has a much larger address space than IPv4. This is based on the

e n on o a - a ress, w ereas v use on y s. e

new address space thus supports 2128 (about 3.41038) addresses.
