AS16617 COMMUNITYISP

Twenty-six blocks under two brands, and the older one still answers with dialled-connection names.

What it's used for

• A community provider's network. Twenty-six IPv4 prefixes announced from the United States, no IPv6, twenty-four thousand three hundred and twenty addresses, through six observed BGP neighbours.

Notable

• The holder line gives a four-letter short form while the AS handle spells it out: the word community and the three letters for an internet service provider.
• The blocks split between two registrants. One is the provider. The other is a county internet council, whose netname is that council's initials with the word for a network, repeated unchanged on five blocks.
• The provider's own netnames run a counter to three and add a fifth style ending in the word total, so five labels cover a single company.
• Registrant fields list roles rather than people: abuse, a spelled-out network operations centre, a technical contact and a support centre.
• Four of eighteen queried addresses answered, across two domains. Three carry an access technology, a two-letter town code and the last two parts of the address; one ends in the word for a fixed address.

Interesting

• A council's name unchanged on five blocks beside a company's on the rest is a community network absorbed by a provider that kept the routing and left the paperwork alone.
• Names that still describe a dialled connection answer today. Reverse zones outlive the technology they were written for, because renaming them breaks logs and buys nothing.
