AS14313 DATABANK-ZCOLO

Seven blocks, six registrants, and one of their names is cut off mid-word.

What it's used for

• A colocation provider's network. 3,840 addresses across seven IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• Only two blocks are registered to the provider, under CV-BLOCK-2-22 and CLEARVIEWMGMT.
• The rest belong to LightBound, LLC under IQUEST-BLK-3, to Latisys-Denver, LLC under MDH-DATA393-209-151-64-0, to McLane Advanced Technologies, LLC with an IT STAFF contact, and to a registrant recorded as First Rate Investmen under the netname UU-63-100-51.
• Seven of eighteen sampled addresses answered, under three unrelated domains including iq-kok-as001-126.iquest.net and 209.151.68-128.static.data393.net.

Interesting

• That truncated registrant is a field limit doing its work in public. Somebody's name was longer than the box allowed, the last letters were dropped without comment, and the record has read that way ever since.
• Six registrants under one AS is the entire business model of colocation, visible in the registry. The provider supplies power, cooling and routing; the customers bring their own addresses, and each acquisition brings another company's records along unchanged.
• One netname begins with two letters belonging to a carrier that has not existed under that name in a very long time, which dates that assignment more precisely than any timestamp in the record.
• One hostname puts dots in the first three parts of the address and a dash before the last. Every generated reverse zone picks a separator, and no two pick the same one.
