AS13370 — NWF-LOCALTEL-ASN-1

AS13370 announces 19 IPv4 prefixes covering 63,744 addresses and 1 IPv6 prefixes.

About this network

Eighteen numbered blocks under one label, and every reverse name is the address with a domain glued on.

What it's used for

• A regional United States fibre and telephone provider. 63,744 addresses across nineteen IPv4 prefixes, two observed BGP neighbours, and the IPv6 block 2604:e00::/32.

Notable

• The netnames run NWF-LOCALTEL-1 through NWF-LOCALTEL-18, with several numbers missing from the announced set.
• The AS handle is NWF-LOCALTEL-ASN-1, matching the netname series.
• Sampled names read 66.172.104.0.nwinternet.com, the four octets in their normal order as separate labels.
• Fifteen of eighteen sampled addresses answered, including ones ending in 0 and in 255.

Interesting

• Putting the address into the hostname in forward order is the opposite of what the reverse lookup system itself does, and it means each name sorts the same way the addresses do. Other providers build the same name backwards because that is the order the query arrives in.
• A numbered series reaching eighteen for a regional provider is eighteen separate trips to the registry, each one a growth step or an acquisition. The gaps are blocks held but not announced, or handed back.
• Two neighbours for sixty-three thousand addresses is a large access network with a very small connection to everyone else: all of these customers reach the internet through two doors.
