isp residential fiber spain

The AS handle TVLOJA is held by Vivafibra Telecomunicaciones, S.L.

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames such as ES-TVLOJA-20090508, LOJA-NET, and GRALOJ-NET.
  • The network announces 7,424 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, a ratio characteristic of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints in the Loja region of Granada, Spain, served via the operator's fiber infrastructure.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing VIVAFIBRA TELECOMUNICACIONES, S.L., while some blocks like 5.154.114.0/24 are registered to AIRE NETWORKS DEL MEDITERRANEO SL UNIPERSONAL.
  • The address inventory is fragmented into multiple /22 and /24 blocks, reflecting historical acquisitions or distinct service segments within the local 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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
