Dominican Republic · AI-generated

cable dsl isp residential

The AS handle AS28118 is held by Altice Dominicana S.A.

What it's used for

  • The address space carries residential access traffic, evidenced by the reverse DNS record adsl-239-254.tricom.net which indicates ADSL service.
  • The network announces 588,288 IPv4 addresses across 299 prefixes and 2 IPv6 prefixes, while maintaining 29 observed neighbours. This high address-to-neighbour ratio is characteristic of an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the largest prefixes, including 152.166.128.0/17 and 181.36.128.0/18, are listed as ALTICE DOMINICANA S.A., matching the AS holder.
  • Altice Dominicana is the Dominican Republic subsidiary of the global telecommunications group Altice, which acquired the local operator Tricom, as suggested by the tricom.net domain in the reverse DNS sample.
  • The inventory consists of large blocks such as 152.166.0.0/17 and 181.36.0.0/18, subdivided into numerous smaller prefixes for distribution.

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 1,773 prefixes, as published 2026-10-13. 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.
