[routing-wg]New ROUTE-SET and RIPE document: Address Space Managed by the RIPE NCC
by leo vegoda 31 May '06

31 May '06

[Apologies for duplicates] Dear Colleagues, We have updated the RIPE document "Address Space Managed by the RIPE NCC" to include references to a ROUTE-SET object describing the address space allocated to the RIPE NCC by the IANA. The new version is ripe-380 and can be found on our web site at: https://www.ripe.net/docs/ripe-ncc-managed-address-space.html We hope the ROUTE-SET object is useful. Kind regards, -- leo vegoda Registration Services Manager RIPE NCC
