AS13409 — PDX - PORTLAND INTERNETWORKS

AS13409 announces 2 IPv4 prefixes covering 8,192 addresses and 1 IPv6 prefixes.

About this network

The reverse names pad every octet to three digits and sit under an unrelated domain.

What it's used for

• A United States internet provider. 8,192 addresses across two IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The AS handle is PDX, a three-letter city code.
• The two blocks are netnames PDX-NET and PDX-NET-2, both registered to the company with an abuse contact.
• Sampled names read 069-064-235-254.graydog.com, with each octet padded to three digits.
• The domain in those names is neither the company's name nor anything in the registry records.

Interesting

• Zero padding makes every hostname the same width, so a list of them lines up in a column and sorts in address order as plain text. Providers who read their own logs by eye do this; providers who feed them to a parser do not bother.
• A reverse domain unrelated to the registered holder usually means a second business, a brand, or an operator running the network on the holder's behalf. The registry names one entity and DNS names another, and both are correct.
• Two /20s under one netname series, with a single upstream, is a provider that grew once and then stayed the size it was.
