About this network

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.
