isp residential spain small

NADUNET-ASN is held by Nadunet Telecom S.L.

What it's used for

  • The address space carries residential and small business internet access, evidenced by netnames such as ES-NADUNET-20171219 and ES-NADUNET-20030114 registered to Nadunet Telecom S.L.
  • The AS announces 1792 IPv4 addresses across 4 prefixes, with 2 observed routing neighbours. This low neighbour count relative to the address inventory indicates an access network providing last-mile connectivity rather than transit.
  • Traffic from this AS consists of subscriber eyeballs for residential and small business customers in the Valencia region of Spain.

Notable

  • Registrants for the three largest prefixes (185.237.180.0/22, 81.172.44.0/24, 185.192.180.0/24) are Nadunet Telecom S.L, matching the AS holder. The smallest prefix 213.162.204.0/24 is registered to NOC NIXVAL with netname Nadunet.
  • The address inventory is small and fragmented, consisting of one /22 and three /24 blocks, typical of a regional ISP that has accumulated space over time.

Reputation

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
