AS20965 — GEANT The GEANT IP Service

AS20965 announces 2 IPv4 prefixes covering 9,216 addresses and 1 IPv6 prefixes.

About this network

The AS handle GEANT is held by GEANT Vereniging.

What it's used for

• The address space carries research and education infrastructure, evidenced by netnames NL-GEANT-20010717 and GEANTIASVRF and reverse DNS entries like test.nmaas.geant.org and test-a10-controller01.geant.org.
• The AS announces 9,216 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 72 observed neighbours; this ratio of moderate address space to high peering density indicates a transit or backbone role for the European research network.

Notable

• Registrants for both announced prefixes are consistent with the announcer, listing GEANT Operations, GEANT Vereniging, and GEANT CERT (formerly DANCERT).
• The address inventory consists of two distinct IPv4 blocks, 62.40.96.0/19 and 83.97.92.0/22, alongside a single IPv6 prefix, 2001:798::/31.
