About this network

The netname begins with the word for a block of addresses, which is the one thing a netname never needs to say.

What it's used for

• A university's network. One IPv4 prefix announced from the United States, no IPv6, two thousand and forty-eight addresses, through four observed BGP neighbours.

Notable

• The netname is six letters meaning a block of addresses, a hyphen, and then the university's name run together with its own word shortened. The first half is redundant with the field it sits in.
• The AS handle keeps only the first word, so the handle is shorter than the netname by everything the netname added.
• The whole announcement is one contiguous block, small by campus standards, registered to the university with no extra contact.
• Four observed neighbours for two thousand addresses is a lot of upstreams for a holding this size.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• The block-of-addresses prefix was a convention from an era when registry records held several kinds of object and the name had to say which. The objects were separated long ago; the prefix stayed on the records that already had it.
• A university with campuses in many places buys connectivity in many places, which is the readable explanation for four upstreams on a small block. The routing is spread wider than the addressing.
• Two thousand addresses is a modern-sized allocation rather than a legacy one. Nothing here was handed out by the block.
