Summary

WebWorld

Ireland · AI-generated

hosting business ireland

The AS handle WEBWORLD-AS is operated by Sternforth Ltd. trading as WebWorld.

What it's used for

  • The address space carries hosting and business services, evidenced by netnames such as IE-WEBWORLD-20040715 and IE-WEBWORLD-20031224, and reverse DNS entries like titan.myhost.ie and ralendovaria.com.
  • The AS announces 14,848 IPv4 addresses across 32 prefixes and 2 IPv6 prefixes, with 12 observed neighbours; this ratio of address volume to peering partners indicates a hosting or business network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes align with the announcer, specifically Sternforth Ltd. trading as WebWorld, though some blocks are registered to Professional Granite Consulting Ltd, Synthetel Corporation, and Internet Utilities Europe and Asia Limited.
  • The address inventory is finely subdivided into numerous /24 and /23 blocks, consistent with an internal corporate estate or segmented hosting environment.

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 1,773 prefixes, as published 2026-10-13. 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.
