About this network

Two separate incident response teams are registered against one block.

What it's used for

• A university network. A single IPv4 /16 announced from Spain, no IPv6, sixty-five thousand addresses, through one observed BGP neighbour.

Notable

• The one block's registrant list names two incident response teams, one belonging to the university and one to the national research network it connects through.
• The university is named twice in the same field, once in each of two languages.
• The netname is three letters, an acronym of the second of those two names.
• Sixty-five thousand addresses are announced as a single route, with no fragments alongside.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Two incident response contacts on one block is unusual and useful. A report about an address here reaches both the university's own team and the wider network's, so nothing depends on one mailbox being read.
• A block this size held by a single university is a marker of early connection, from when address space was granted on request rather than justified by headcount.
• No IPv6 from a research and education network is the finding that sits oddly. These networks were the first to deploy it, and this one has not.
