AS13457 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

One netname writes the block's address backwards, and another still calls a /24 a class C.

What it's used for

• An electric generation cooperative's network. 768 addresses across three IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 74.204.84.0/24 is netname USSIG-0-84-204-74-24, the address written in reverse octet order.
• 104.167.194.0/24 is netname WPSCI-CLASS-C.
• 12.178.147.0/24 is netname ATT, registered to the carrier rather than the cooperative.
• Sampled reverse names read customer-74-204-84-64.host.ussignalcom.net, in forward order.
• First seen in the routing archive on 2000-10-31, an actual date rather than the archive's start.

Interesting

• The same provider writes the address one way in the registry and the other way in DNS. Reverse lookups are stored backwards by design, so a tool that generates names from the query and a tool that generates netnames from the allocation disagree about which end comes first.
• A class C was the old fixed-size unit of address space, retired when routing moved to variable-length prefixes. Naming a block that in the registry dates the record and tells you the person writing it learned addressing before the change.
• A power cooperative generates for other cooperatives rather than selling to households, so what it needs from the internet is small and steady: three /24s, two upstreams, nothing growing.
