Summary

SW Hosting

Spain · AI-generated

hosting cloud datacenter business

The AS handle SWHO-AS is held by SW Hosting & Communications Technologies SL.

What it's used for

  • The address space carries hosting and cloud infrastructure, evidenced by reverse DNS entries pointing to swhosting.com and netnames ES-SWEB-20060228 and ES-SWEB-20140619.
  • The network announces 5120 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a hosting provider rather than a transit or access network.
  • Traffic from this AS consists of web hosting, domain registration, cloud VPS, and data center services for business clients.

Notable

  • Registrants for both announced prefixes match the AS holder, sw hosting & communications technologies SL.
  • The address inventory consists of two distinct IPv4 blocks, 81.25.112.0/20 and 185.61.124.0/22, with no IPv6 prefixes in inventory.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
