LAN

Local Area Network

Local network consisting of computers usually located in a building or a group of buildings and sharing one or more private IP addresses.

Antonym: WAN (Wide Area Network)

 

LIR

Local Internet Registries

The Internet addressing and routing resources – consisting of IP addresses and AS numbers - were distributed by the IANA to the RIRs.

There are currently four RIRs: ARIN for the North America and Africa regions, APNIC for the Asia-Pacific regions, LACNIC for the South America - Caribbean regions, RIPE NCC for the extended Europe zone and AFRINIC for the African regions.

The RIRs then allocate those resources to Local Internet Registries that allocate IP addresses to end users.

The LIR is responsible for receiving IP address requests, processing these applications by allocating networks, and updating the corresponding databases.
