Hosting ARIN
Summary
TierraNet Inc.
hosting enterprise legacy
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.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
