About this network

The network of the City of Portland, Oregon.

What it's used for

• Municipal government systems. One /22 of 1,024 addresses with three observed BGP neighbours, no IPv6 announced.

Notable

• A single announcement, 74.120.152.0/22, registered under the netname CITY-OF-PORTLAND-OR-USA — the same string used as the AS handle.
• The sampled reverse name is 254.154.ptldnet.portlandoregon.gov: the last two octets in reverse order, then ptldnet for the city network, under a .gov domain.
• First seen in the routing data in June 2007.

Interesting

• Three upstreams for one /22 is more redundancy than the address count suggests. A city runs emergency dispatch, water and traffic systems on the same network as its payroll, and the cost of a third circuit is small against any of those going dark.
• Portland's .gov is worth putting next to Aurora's ci.aurora.co.us at AS12156. Both are city networks of similar size; one moved to the federal government namespace and one stayed in the geographic .us hierarchy that was originally meant for exactly this purpose. The .us scheme lost because .gov carried authority that a hierarchy of place names never did.
