Summary

City of Memphis

United States · AI-generated

government infrastructure business

A netname from the era when a city network was called a metropolitan area network.

What it's used for

  • A municipal government's network. 2,048 addresses across two IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

  • 167.29.0.0/22 carries the netname MEMPHIS-MAN, registered to the city with a DNS administration role contact.
  • The registry lookup for 167.29.12.0/22 failed, so nothing is known about that block's record.
  • The two blocks sit in the same range with a gap of eight blocks between them.
  • Six addresses were queried for reverse DNS and none returned a name.

Interesting

  • The three letters at the end of that netname stand for metropolitan area network, a term for the city-scale fibre rings that municipalities and universities built to join their own buildings together, in the decade before this AS was first seen routing. The technology behind the phrase is long gone and the name outlived it, which is the usual fate of a registry field.
  • Naming a DNS administrator as the contact is a small piece of good practice, since address records and name records are managed by the same people and most registrations name neither.
  • The gap between the two blocks is space the city either never received or gave back, and it costs a second announcement to work around.
  • Two upstreams and nothing published fits a network carrying payroll, permits, police and traffic systems that have no reason to be reachable by name.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
