Peering Policy

DSM (GB) (AS48070) operates an open policy and will generally welcome all requests for peering.

We do not require a signed agreement but are happy to do so where the agreement is reasonable.


  • Hot-potato routing is implied. MEDs are not honoured.
  • Settlement free peering.
  • Neither party should ever establish a gateway of last resort configured towards the other party’s network.
  • A minimum of 5 Mbit/s is generally recommended but not required.
  • We reserve the right to refuse peering with any party.
