About this network

A university announcing two hospitals, a research network, and a netname that labels the wrong octets.

What it's used for

• A university network carrying affiliated teaching hospitals. Ten IPv4 prefixes and one IPv6 /48 announced from Canada, one hundred and forty-eight thousand addresses, through one observed neighbour.

Notable

• Two of the blocks are /16 allocations, from an era when universities were given space on that scale.
• Two hospitals hold their own registrations inside this routing, each with a netname naming the institution, the province and the country.
• One block is registered to the provincial research network under a netname citing octets that do not match the block it labels.
• One /24 is named for guest access and the roaming federation used between institutions, so the registry states which range carries visitors.
• Three of eighteen sampled addresses answered, each naming a hospital site and a research institute before the university's domain.

Interesting

• Naming the guest range in the registry is honest and useful, and it also tells anyone scanning which addresses belong to devices the institution does not control.
• The hospital reverse names identify the building from the address alone, which is exactly what an operator wants during an incident and rather more than a stranger needs.
• A netname pointing at the wrong octets is harmless until someone automates from it, at which point the block is attributed to a range it has nothing to do with.
