The AS handle UNIVERSIDAD AUTONOMA DE YUCATAN is held by Universidad Autónoma de Yucatán.

What it's used for

  • The address space is registered under the netname 148.209.0.0 - 148.209.255.255 with registrant UNIVERSIDAD AUTONOMA DE YUCATAN, indicating a dedicated institutional network.
  • The AS announces 65536 IPv4 addresses across 31 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.

  • All sampled registrants match the announcer, consistently listing UNIVERSIDAD AUTONOMA DE YUCATAN for the major prefixes.
  • The address inventory is finely subdivided into 31 IPv4 prefixes within the 148.209.0.0/16 range, reflecting internal site-by-site segmentation typical of a large corporate or academic estate.

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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
