About this network

Four separate addresses all answer with the same name, and that name is the abbreviation for the record type itself.

What it's used for

• A broadband and hosting provider. 83,712 addresses across seven IPv4 prefixes, the IPv6 block 2001:5b8::/32, and one observed BGP neighbour.

Notable

• 216.242.0.0/16 is netname WEBUNITED and 66.115.0.0/18 is WEBUNITED-NET2, a brand the registrant name does not contain.
• Four blocks are netname HOST-BROADBANDONE, and 64.139.220.0/24 is netname CCCL-46, registered to a two-character company name.
• Four sampled addresses all answer as ptr.host.net, the same string for each.
• Others answer as 8315-ibe-cust.host.net and es01.ptree.bct.host.net.

Interesting

• A reverse record whose name is the abbreviation for reverse records is a placeholder that escaped into production. Somebody's template had the field name where the value should go, and four addresses now share a hostname that identifies nothing.
• Because these names are not unique, anything that treats a reverse lookup as an identity check will group unrelated addresses together, which is the practical cost of a placeholder nobody noticed.
• The older brand surviving in two netnames while the current one appears in four is the company's history in one field: a /16 and a /18 from the first name, smaller blocks from the second.
