AS13409 PDX - PORTLAND INTERNETWORKS
Unclassified ARIN
Summary
Portland Internetworks
isp hosting business
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-NETandPDX-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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 452 networks and 1,853 prefixes, as published 2026-11-05. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
