IP Network

An IP network is a group of computers or devices connected via their unique internet protocol (IP) addresses. Each address has to be unique. Amateur Radio has had since the start of IP protocols the 44.x.x.x range. Using the AREDN firmware, the range used in 10.x.x.x


The Optimized Link State Routing Protocol (OLSR) is an IP routing protocol optimized for mobile ad hoc networks. This is used within the AREDN systems.


BGP (Border Gateway Protocol) is the protocol underlying the global routing system of the internet. It manages how packets get routed from network to network through the exchange of routing and reachability information among edge routers.


An Autonomous System (AS) is a group of IP networks run by one or more network operators with a single, clearly defined routing policy. When exchanging exterior routing information, each AS is identified by a unique number: the Autonomous System Number (ASN). An AS is also sometimes referred to as a routing domain. Current RIPE Policy requires a network to be multi-homed, and have a unique routing policy for an ASN to be assigned. Requests must show the routing policy of the AS. (see article)

The control list used by AMPR.org is here.

Within the Amateur Radio Community, we have a private range allocated to use in both the 16 bit and 32 bit range. The 16bit range is nearly fully utilised, but the 32 bit range is available.

32-bit-numbers for private usage in AMPRNettm have to be in the range of 4200000000 to 4294967294 (RFC 6996).

The UK allocation is 4223400000 to 4223599999
