Network type: residential

AS13692 announces 26 IPv4 prefixes covering 45,312 addresses and 1 IPv6 prefixes.

About this network

A lettered series of netnames that skips from C to G, and two reverse-naming schemes that disagree about which way an address runs.

What it's used for

• A rural broadband provider. 44,288 addresses across twenty-five IPv4 prefixes, the IPv6 block 2607:8600::/32, and nine observed BGP neighbours.

Notable

• Five blocks are netname DOUGLAS-FAST-NET- plus a single letter, using A, B, C, G and H.
• Two more are DOUGLASCTYOR-64 and DOUGLASCTYOR-199, a county, a state code and the block's first octet, registered to the county itself.
• 198.237.16.0/20 is netname DOUGLAS-ESD, registered to an education service district.
• Two blocks are netname COGENT-A, registered to a transit provider.
• Some addresses answer as 67-219-228-0.mycomspan.com, with hyphens and a third brand.
• Others answer as 100.42.171.254.douglasfast.net, with the address in its normal order and dots.

Interesting

• A lettered series missing three letters means those blocks were returned, transferred or never cut. The gap is the only surviving evidence that they existed at all.
• One provider using hyphens in one zone and dots in another gives two hostnames for two addresses on the same network that a parser has to handle differently, which is the practical cost of a rebrand that only half happened.
• A county government, a school service district and a commercial provider sharing one AS is what rural connectivity actually looks like: whoever could get the space pooled it behind one set of upstreams.
