AS13688 — PSEG

AS13688 announces 3 IPv4 prefixes covering 2,560 addresses and 0 IPv6 prefixes.

About this network

A utility on one upstream, with its own name spelled three different ways across three registry fields.

What it's used for

• An electric and gas utility's network. 2,560 addresses across three IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• Two blocks are netname PSEG3, an abbreviation with a counter.
• 208.208.47.0/24 is netname UU-208-208-44-A, a former carrier's prefix followed by an address three ranges below the block it names, plus a letter.
• The AS holder is the parent group, while the blocks are registered to the operating company, once with the word for company at the end and once without it.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• A netname pointing at a different address than the block it sits on is the parent allocation's name inherited by a piece cut out of it. The field describes where the space came from rather than where it is.
• One upstream for a utility that runs power and gas for millions of people is the routing table showing only the corporate side. Grid control networks are not in it, and are not supposed to be.
• Three spellings of one company across holder, registrant and netname is normal registry drift, and it is why matching networks to organisations by string comparison quietly fails.
