About this network

A connector manufacturer's network, held across two blocks with unrelated histories.

What it's used for

• Corporate connectivity. 512 addresses in two /24s with a single observed BGP neighbour and no IPv6 announced.

Notable

• 63.116.253.0/24 is netname UU-63-116-253-D5 — a label generated in UUNET's scheme — registered to Amphenol Corp with an abuse contact.
• 192.88.132.0/24 is netname BCOENET, also registered to Amphenol, and the name matches nothing else in the record.
• The AS handle is AAO-AIO, two sets of initials that appear nowhere else either.

Interesting

• Amphenol grew by acquisition across decades, buying connector and cable businesses in aerospace, defence, industrial and automotive markets and keeping them running under their own names. Records like BCOENET are what that leaves behind: a netname belonging to an operation that was absorbed, updated in the registrant field and nowhere else.
• The 192.88 block is early class C space and the 63.116 block came from UUNET a decade later. One company, one AS, and two eras of how you got addresses — a paper request in the first case, a service provider assignment in the second.
