AS10732 TIERRANET

TIERRANET is TierraNet Inc., a long-running San Diego web-hosting company and domain registrar. It is best known publicly under its DomainDiscover brand, and the reverse DNS in this AS confirms the identity from several directions at once.

What it's used for

This is shared-hosting and domain-services infrastructure. RIS counts 2 announced IPv4 prefixes carrying 16,384 addresses — two /19s, 216.104.160.0/19 and 209.240.128.0/19 — with no IPv6 and just 1 observed neighbour. RIS also sees a set of more-specific /24s carved out of the 216.104.160.0/19, which is ordinary traffic-engineering or segmentation inside an operator's own block rather than evidence of a separate network.

The rDNS is the whole story. ns3.domaindiscover.com is an authoritative nameserver for TierraNet's registrar business; smtp01-smtp-3.daemonmail.net and smtp02-smtp-3.daemonmail.net are mail platform hosts; servd3.tierra.net and callcenter2.tierra.net are the company's own servers and voice infrastructure. And then there is sacramentosecretaryofstatefilingservices.com — a customer's vanity domain sitting on a hosting IP, which is exactly what shared hosting looks like when you sample it: a customer's chosen hostname rather than a provider-generated one.

Notable

A single observed neighbour means this network is effectively single-homed at the time of observation — a notably lean posture for a hosting provider, where most operators buy at least two upstreams. It is the routing profile of an established, self-contained hosting shop rather than a growth-stage cloud.
