About this network
Two contacts are listed, and both are named after what they do rather than who they are.
What it's used for
- A university's network. One IPv4 prefix announced from Canada, no IPv6, sixty-five thousand five hundred and thirty-six addresses, through two observed BGP neighbours.
Notable
- The AS handle is the university's name shortened to six letters, and the netname is the same six letters. The two identifiers are identical, which is rarer here than it should be.
- The block lists two extra contacts beside the university. One is the word for technical, cut short; the other is the word for complaints. Neither names a person or a team.
- The whole announcement is one block at the largest prefix size in common use, held under a single registration.
- Three addresses were queried for reverse DNS and none returned a name.
- Two observed neighbours carry everything.
Interesting
- Contacts named after their function are the correct answer to a problem every registry record has: people leave, roles do not. The cost is that the record tells you nothing about who is actually reading the mail, and the benefit is that somebody probably still is.
- A single unbroken block of this size at a mid-sized university is a receipt for arriving early rather than a measure of how much is in use. The size was set by what was easy to hand out at the time.
- Nothing in reverse DNS is the campus default. Students and staff need names resolved inward; almost nothing on the network needs to be found from outside.
