IPIP Mesh/Gateways: Difference between revisions

Latest revision as of 19:08, 29 September 2026

Much of the AMPRNet address space is interconnected via gateways that implement IPENCAP (IP Protocol Number 4) encapsulated tunnels. These tunnels provide endpoints for the AMPRNet address space allocated to a particular region or end user, effectively forming a mesh network of interconnected tunnels between AMPR subnets. The Portal maintains a database of all the gateways, their public IP addresses, and the subnets they serve. This routing information is distributed via modified RIP advertisements. A complete list of gateways can be downloaded from the Portal API.

In order to keep this database up to date, everyone that operates a gateway must register on the Portal and have their gateway(s) assigned to their account and associated with their allocation(s).

In addition to the gateways operated by users who connect via IPENCAP tunnels, traffic exchanged between the ARMPNet mesh and the public Internet is routed via the Amprgw – please see the Amprgw page for important details on passing traffic between the public Internet and the IPENCAP tunnel mesh.

-A lot of the 44/8 address space is interconnected via [[gateway|gateways]]. These are IPIP encapsulated [[tunnel|tunnels]] that carry the 44/8 address space allocated to a particular region or end user. There exists a database of all the gateways public IP addresses and the subnets they service on the [[portal]]. This database generates a file called [[encap.txt]] which is basically a routing table that specifies which subnets can be reached via which gateway.

-As the portal only went live recently, we are in a transition phase, where all the old gateway entries that existed have been copied into the new database and are awaiting their "owners" to claim them. After a suitable period of time has elapsed, about a year, any unclaimed gateways will be removed from the system, thus ensuring that the database is as up to date and as accurate as possible. It is therefore important to register and claim your gateway asap!
