residential isp fiber wisp

CODISATS is operated by Codisa Telco Solutions S.L.

What it's used for

  • The address space carries residential and wireless subscriber traffic, evidenced by reverse DNS entries such as clientes.biwifi.es and cdnet.es, alongside netnames BIWIFI, CodisaTS_NOC, and ONDAFIBRA.
  • The AS announces 2048 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 30 observed neighbours; this ratio indicates an access network providing last-mile connectivity rather than a transit provider.
  • Traffic consists of end-user internet access for residential customers, utilizing both fiber and wireless (WISP) technologies as indicated by the wisphs subdomain in reverse DNS.

Notable

  • Registrants include CARMIPERE S.L., ONDAFIBRA S.L., and generic abuse roles, suggesting the AS aggregates space from multiple related entities or brands under the Codisa umbrella.
  • The inventory includes a /22 block (2.57.4.0/22) registered to CARMIPERE S.L., which is distinct from the primary Codisa netnames but announced under the same AS.
  • The address inventory is a mix of smaller /23 and /24 blocks and one larger /22, reflecting a portfolio of acquired or leased ranges for different service brands.

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: 447 networks and 1,843 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.
