cable residential isp spain

CWSANVICENTE-AS is operated by Fibraworld Telecom S.A.U.

What it's used for

  • The address space carries residential cable access traffic, evidenced by reverse DNS entries such as 45.9.133.255.mutxamell.cableworld.es and 212.63.105.255.elda.cableworld.es.
  • The network announces 5632 IPv4 addresses across 6 prefixes and maintains 2 observed neighbours, a ratio indicative of an access/eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs connected via cable infrastructure in specific Spanish municipalities.

Notable

  • All registrants for the announced prefixes are FIBRAWORLD TELECOM S.A.U., consistent with the AS holder.
  • The netnames (e.g., ES-CABLEWORLDELDA-20190418) and reverse DNS hostnames reference specific towns like Elda, Mutxamel, and San Vicente, reflecting a local service footprint.
  • The inventory consists of six /22 and /23 blocks, all located in Spain.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
