isp legacy

Internet Cancún S.A. de C.V. (cancun.net.mx), a regional internet service provider operating from Plaza las Flores on Avenida Uxmal in Cancún, Quintana Roo. The ASN has been registered to the company since 1996 and announces about 1.8k IPv4 addresses.

What it's used for

  • Retail internet access around Cancún — the provider sells residential connectivity that does not require a phone line, and reaches outlying areas that are hard to serve with fixed lines.
  • Reverse DNS across the space is consistently under cancun.net.mx (200-33-190-10.cancun.net.mx, ei-189-5.cancun.net.mx), with business and institutional customers visible too — including hosts belonging to a local university.

Notable

  • Eyeball address space for a small regional operator, not hosting or transit. The routed footprint is four prefixes.
  • One announced block, 200.36.45.0/24, still carries reverse DNS under uninet.net.mx (Telmex's network), a leftover of address space originally delegated from the incumbent.

Interesting

  • A single small ISP holding a sub-7500 AS number is a reminder that in the mid-1990s any organisation running BGP could get one — scarcity came later.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
