About this network

The registry itself is listed as the abuse contact, because the holder never named one.

What it's used for

• An open university's network. One IPv4 /19 announced from Spain, no IPv6, eight thousand addresses, across two observed BGP neighbours.

Notable

• The block's second registrant is the registry's own abuse handling role rather than anyone at the university, which is what appears when a holder leaves that field to the default.
• The netname is the country code, a four-letter acronym and an allocation date, following the convention exactly.
• Eight thousand addresses are announced as a single route with no more specific pieces.
• No IPv6 is announced.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• An abuse report about this network goes to the registry, which forwards it or does not. That is one more hop and one more delay than a directly named contact, and it is a common default.
• A single route for the whole holding is the tidiest possible announcement. It also means the university has never needed to steer traffic to part of its space separately.
• No IPv6 from a university is unusual, since research and education networks were generally among the first to deploy it.
