Summary

TECHOFF SRV LIMITED

Andorra · AI-generated

hosting dedicated vps offshore

DMZHOST is TECHOFF SRV LIMITED, trading as dmzhost.co — an offshore VPS and dedicated-server host that markets explicitly on DMCA-ignore and offshore positioning.

What it's used for

VPS and dedicated-server hosting. RIS observes 3 IPv4 prefixes totalling 768 addresses and no IPv6: 45.148.10.0/24, 93.123.109.0/24 and 195.178.110.0/24. 45.148.10.0/24 is netname DMZHOST, registered to TECHOFF SRV LIMITED with country Andorra. Transit comes from a single upstream, AS57717. There is no PeeringDB record.

The catalog is VPS, storage and dedicated servers. There is no VPN product on the site.

Notable

  • Three names, one company, which makes whois lookups confusing: the aut-num is named DMZHOST, the RIPE org is TECHOFF SRV LIMITED (ORG-TSL73-RIPE), and the trading brand is dmzhost.co. Spamhaus records the domain as dmzhost.co with country SC (Seychelles), while the inetnum says AD (Andorra).
  • Offshore positioning is the entire marketing pitch. The site returns 65 matches for DMCA / offshore / bulletproof / "ignore" language against 44 mentions of VPS or dedicated servers. That is a statement about abuse policy, not about what kind of operator this is — it sells servers.
  • Reputation is the strongest signal set of any network in this group: listed in Spamhaus ASN-DROP, 45.148.10.0/24 in Spamhaus DROP as SBL678435, and an FBI IC3 indicator inside the space at 45.148.10.212 — advisory 260702, "Cyber Criminal Group TeamPCP" (2026-07-02).

Interesting

  • Reverse DNS is empty across all three prefixes on every sampled address, so there is no tenant-brand surface at all — unusual for a host this heavily marketed.
  • 768 addresses behind one upstream is a very small footprint for a network with this much reputation attached to it. Density of abuse per address, rather than scale, is what puts it on lists.
  • The AS number dates to 2019-09-05, so unlike most offshore hosts that surface on blocklists, this one is not a freshly-registered shell.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,782 prefixes, as published 2026-10-16. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
