isp residential catalonia broadband

The AS handle XTA-AS is held by Xarxes de Telecomunicacions Alternatives SL.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as 2-57-109-255.ipv4.xta.cat and 185-73-169-255.xta.cat.
  • The network announces 7,680 IPv4 addresses across 9 prefixes and 2 IPv6 prefixes, while maintaining only 2 observed routing neighbours. This high address-to-neighbour ratio indicates an access network providing last-mile connectivity rather than transit.
  • As a regional ISP operating in Catalonia, the traffic consists of subscriber eyeballs connecting to the internet via fixed-line broadband services in towns such as La Granada and Vilanova i la Geltrú.

Notable

  • Registrants for the majority of prefixes are consistent with the announcer, listing Xarxes de Telecomunicacions Alternatives SL with netnames like ES-XTA-20190319 and ES-XTA-20141017.
  • One prefix, 45.131.30.0/24, is registered to CARTAGO TELECOM S. L. under the netname ES-CARTAGO-20190718, indicating a distinct ownership or leasing arrangement for that specific block.
  • The inventory is composed of multiple /22 blocks and two /24 blocks, all located in Spain, with a single /32 and /29 for IPv6.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
