LOA: Letter of Authorization ip announcement and/or acceptance Print

  • 248

Serverius is able to announce and/or accept your private IPv4 and IPv6 subnets under the Serverius ASN or your own AS number to use on your own router. Serverius will accept it ONLY by a signed LOA.

  • If you want us to announce your IP subnets on the Serverius ASN, we need a LOA with the subnets you want us to announce. Your subnets announcement configuration will be announced for  199,- EUR (one time) + yearly fee of 162,- EUR.
  • If you are running your own ASN on your own router (GRE tunnels are supported) behind the Serverius network, we need a LOA with only your ASN. All IP subnets behind the ASN will be accepted free, based on proper RIPE database (route object) description. Also, updates afterward are free of charge.

Below an example of what you can use as a template.

  • All IP subnets are announced by the Serverius private network: https://serverius.net/connectivity/ip-transit-amsterdam/ Ip space is announced by all connect peering and transits of the Serverius IP network.
  • Max 1 AS numbers and/or 10 IP subnets per LOA. If you have more subnets, you need to send us multiple LOA's.

Ripe justifications

  • When your IP space is registered at Ripe, and you want Serverius to announce it by its routers, Serverius will need to make a route object in the Ripe database. To do that, in the Ripe database you need to add "serverius-mnt" as "mnt-routes". Only with this set, Serverius is able to add the route object on your IP space.
  • When your IP space or ASN is registered at Ripe, and you want to announce it by your own router under your own (main) ASN, Serverius will add the import and export settings in the Ripe database.
