Summary

Partan & Partan

United States · AI-generated

enterprise legacy

A small independent network (PARTAN-LAB) registered to Partan & Partan of Takoma Park, Maryland, the practice of long-time network engineer Andrew Partan.

What it's used for

  • A handful of /24s announced from a small private network — a lab and consulting network rather than a commercial service provider.
  • Address space includes blocks out of ranges historically associated with early US internet exchange and backbone infrastructure.

Notable

  • Tiny by address count, but it holds its own AS number and speaks BGP — the classic profile of a network run by someone who works on the internet for a living and wants their own routing policy.
  • Andrew Partan is a familiar name in early internet engineering circles, including contributions to the BIND DNS server.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
