AS13606 announces 2 IPv4 prefixes covering 768 addresses and 0 IPv6 prefixes.

About this network

A city announces a university system's block alongside one its cable provider registered for it.

What it's used for

• A municipal government's network. 768 addresses across two IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 206.77.104.0/23 is netname THENET-CIDR-5, registered to a state university system.
• 65.36.60.0/24 is netname GRANDECOM-CITYOFLEANDER, registered to the city.
• Three of six sampled addresses answered, as 65-36-60-64.static.grandenetworks.net and similar.
• The AS handle ends in a counter, implying a second number was expected.

Interesting

• A city holding space from a higher education network is a leftover from how regional connectivity was built. Universities ran the networks that everyone else joined, so municipal and school district addresses were assigned out of academic allocations and never moved.
• That netname says the object was cut when addressing switched from fixed classes to arbitrary prefix lengths, and it was the fifth such block. It is a dated artefact used daily.
• The other block's netname joins the provider to the customer, and the reverse names sit under the provider's domain, so an outsider learns who the city buys its connectivity from before learning anything about the city.
