Summary

ICDSoft

Global · AI-generated

hosting legacy

ICDSoft Ltd (ICDSoft) — a long-running web-hosting company, headquartered in Sofia, Bulgaria, that has been selling shared hosting since the late 1990s. Around 15,000 IPv4 addresses across 30 prefixes.

What it's used for

  • Shared web hosting, email and domains. The reverse DNS is a hosting provider's fingerprint, top to bottom: sequential shared servers named sNNNN.sureserver.com, their nameservers as ns2.sNNNN.sureserver.com, cage switches and VLAN gateways named the same way, plus white-label nameservers for reseller brands.
  • sureserver.com and suresupport.com are the company's own infrastructure domains — the customer-facing brand and the technical estate are deliberately kept apart.

Notable

  • A textbook case of the scattered-multi-RIR shape being innocent. The inventory spans ARIN (216.34/216.35, 64.14, 209.67), APNIC (116.251) and RIPE (195.42, 195.8, 213.145) blocks — the silhouette of an address broker — but every block carries first-party sureserver.com reverse DNS and is registered to ICDSoft itself. It is simply a hosting company with data centres on several continents, which is exactly what its geographically-split blocks say.
  • Location is best described as Global: the ARIN space serves US customers, the APNIC space Hong Kong, the RIPE space Europe, all from one operator.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
