AS14955 — N-V-C

AS14955 announces 4 IPv4 prefixes covering 22,528 addresses and 0 IPv6 prefixes.

About this network

Five prefixes, one registrant, one upstream, and reverse names that write every address backwards.

What it's used for

• A rural telephone company's broadband network. 22,528 addresses across five IPv4 prefixes, with a single observed BGP neighbour and no IPv6 announced.

Notable

• All five blocks are registered to Northern Valley Communications LLC with a NOC contact, under netnames NOVC, NOVC-02, NOVC-03 and NOVC-04.
• Two adjacent /20s, 64.68.160.0/20 and 64.68.176.0/20, share the plain NOVC netname; the numbered ones came later.
• Seven of fifteen sampled addresses returned a name, every one of the form 0.104.35.66.nvc.net and 254.187.68.64.nvc.net.

Interesting

• Reversing the octets makes the label match the order used by the reverse lookup itself, so generating the zone is a copy rather than a transformation. It is the cheapest scheme to implement and the hardest to read aloud.
• The numbering tells the acquisition order without needing a date. The unnumbered block came first, and each later purchase took the next integer, so the netnames are a timeline.
• One neighbour carrying 22,528 addresses means one upstream. For a cooperative in a thinly populated county there may not be a second fibre route to buy, and the redundancy that exists is inside the provider's own network rather than in the routing table.
• Five announcements for five allocations is a network that has never needed to split a block for traffic engineering, which is the quiet luxury of having exactly one exit.
