About this network

Two different addresses answer with the same hostname, and that hostname is the word for the record type itself.

What it's used for

• A web hosting provider's network. 13,312 addresses across five IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced. First seen in 2000.

Notable

• 174.136.64.0/19 carries APPLIEDINNOVATIONS and 216.167.192.0/20 carries AI-NET1, both registered to Applied Innovations Corporation.
• Two blocks carry the netname ML-1211, registered to Quantified IT, and one carries HOST-BROADBANDONE, registered to BroadbandONE, LLC.
• Four of fifteen sampled addresses returned a name: ip-174-136-87-254.hostedbyappliedi.net, listmanager.appliedi.net, and ptr.host.net twice.

Interesting

• Two distinct addresses answering ptr.host.net is a placeholder that escaped. Somebody needed a default reverse name, typed the record type as the label, and it has been answering ever since. Mail servers that check whether a name maps back will accept it, which is usually all that matters.
• The hosting brand and the corporate brand live in different domains: customer machines sit under hostedbyappliedi.net, while a named internal service sits under appliedi.net. Separating the two keeps a customer's shared address off the company's own domain.
• Three registrants across five blocks on a network this small means most of the space is borrowed or acquired rather than allocated.
• Two neighbours is thin for a hosting provider, and it makes the upstream relationship the single most important thing about this network.
