About this network

A provincial research network announcing government, university and college space under one number.

What it's used for

• A not for profit research and education network. Fifty-four IPv4 prefixes and two IPv6 prefixes announced from Canada, twenty thousand addresses in total, across thirty-five observed neighbours.

Notable

• Eight of the sampled blocks share one netname belonging to the provincial government, even though they sit in unrelated parts of the address space and are announced as separate routes.
• That netname ends in a four figure number, a size marker from an era when allocations were counted in addresses rather than described by prefix length.
• Other blocks are registered to a university and a college under their own netnames, so the routing carries at least four distinct institutions.
• The three answering addresses all use the same form: the word host, the full address written with its dots intact, and then the network's domain.
• Eighteen addresses were queried for reverse DNS and three returned a name.

Interesting

• Embedding the address with its dots means each octet becomes its own label in the name, so the reverse name has seven parts where most have three or four. It parses, it is unambiguous, and it makes the network's naming instantly recognisable in any log.
• Thirty-five neighbours for twenty thousand addresses is the signature of a research network. These peer widely by design, because carrying traffic between institutions is the point rather than a cost.
• One netname across eight scattered blocks is a single allocation record that routing has since fragmented.
