Summary

Onlycable

Spain · AI-generated

isp residential fiber spain

The AS handle ONLYCABLE-AS is held by Onlycable Comunicaciones S.L.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as red-servicios.onlycable.es and netnames like ES-ONLYCABLE-MU.
  • With 17,920 IPv4 addresses announced across 29 prefixes and only 1 observed neighbour, the network functions as an access provider rather than a transit carrier.
  • Traffic consists of subscriber eyeballs and local business connectivity for a telecommunications operator providing services in the Cartagena region of Spain.

Notable

  • Registrants are consistent with the announcer, appearing as Onlycable Comunicaciones S.L., ONLYCABLE SL, and ONLYCABLE FIBRA SL across the largest prefixes.
  • The address inventory is fragmented into multiple /22 and /23 blocks, reflecting historical acquisitions or regional expansion within the Spanish market.

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: 436 networks and 1,769 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.
