About this network

A community bank announcing a /24 whose registry record names two dead carriers' worth of history.

What it's used for

• Corporate connectivity. 256 addresses in a single /24 with one observed BGP neighbour and no IPv6 announced.

Notable

• The block, 168.215.212.0/24, is netname TWTELECOM-COM, registrant Level 3 Parent, LLC.
• Neither of those names is the bank's. The AS handle, CWBANKNET, is the only place the bank appears.
• One prefix, one neighbour, no IPv6.
• The registrant field says Parent, which is a holding-company entity rather than an operating one.

Interesting

• tw telecom was a business-focused carrier absorbed by Level 3, and Level 3 was itself absorbed afterwards. The netname preserves the first company and the registrant preserves the second, so a single record holds two acquisitions in sequence and mentions neither the current owner nor the customer using the addresses.
• This is what makes registry data awkward to read as ownership. The fields are accurate about who was assigned what and when, and almost silent about who runs it now, because updating them after a merger is work that benefits nobody in particular.
• A bank on one upstream with carrier-registered space is the normal small-institution arrangement: the AS number buys the option to leave, not a second path today.
