About this network

Three initials, one block, and a contact who is a job rather than a person.

What it's used for

• A disaster research centre's network. One IPv4 prefix announced from the United States, no IPv6, one thousand and twenty-four addresses, through two observed BGP neighbours.

Notable

• The AS handle is three initials, one for each word of the centre's name, and nothing else.
• The netname is those same three initials with the word for a network appended, which adds nothing the field did not already imply.
• The block lists an extra contact beside the centre: a job title in two words, naming the role rather than whoever holds it.
• The whole announcement is one contiguous block, and it is the entire holding.
• Two observed neighbours carry it, which for an organisation whose work assumes things break is the minimum worth having.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• An organisation built around disasters keeping two upstreams and a single small block is a reasonable reading of its own advice: modest, redundant where it matters, and not dependent on any one supplier.
• A job title as the registry contact is the right answer for a place where the work outlives the staffing. It also means an outside report goes to a role, and whether anyone reads it depends on whether the role is currently filled.
• A thousand addresses is a research group's footprint. The interesting output is data and warnings, and neither needs a large public network to leave the building.
