AS13839 — P1P3R

AS13839 announces 3 IPv4 prefixes covering 1,536 addresses and 0 IPv6 prefixes.

About this network

The AS handle spells the firm with digits standing in for letters.

What it's used for

• An investment bank's network. 1,536 addresses across three IPv4 prefixes, four observed BGP neighbours, and no IPv6 announced.

Notable

• The AS handle is P1P3R, a five-character string using digits in place of two of the letters.
• All three blocks are netname PJC-INDEPENDENT, initials followed by a word.
• The middle initial matches nothing in the registrant's current name.
• All three prefixes begin 206.15, pieces of one parent range announced separately.
• First seen in the routing archive on 2005-08-23, timestamped at midnight.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• Digit-for-letter substitution in a registry handle is a choice nothing required. Registry handles must be unique, so the usual cause is that the plain spelling was already taken, and the workaround has now outlived whatever conflict produced it.
• The netname's initials record a name the firm no longer uses, and the word attached to them describes a status rather than a network. Together they date the object to a corporate era the registrant field has already moved past.
• Three announcements from one parent range, four upstreams, no IPv6, and no reverse names is a bank publishing the minimum.
