Summary
Altice Dominicana
isp eyeball dsl legacy
A Dominican access provider, part of the Altice group, running on the network Tricom built.
What it's used for
- Residential and business access. 1,536 addresses over six
/24s with one observed BGP neighbour, no IPv6 announced.
Notable
- Every sampled address returns a reverse name under
tricom.net, and all eighteen queried answered — an unusually complete result. - Those names sort the space by service:
adsl-1-64.tricom.netfor broadband,ip-159-64.tricom.netfor general assignments, andLeaseLine-001-64.tricom.net, in mixed case, for dedicated circuits. - The netnames are not names at all. Each is the literal address range the block came from —
148.103.0.0 - 148.103.255.255,190.94.64.0 - 190.94.127.255— which is how LACNIC records assignments.
Interesting
- Tricom was one of the Dominican Republic's own telephone companies before Altice bought its way into the market, and the acquired network still answers to the acquired name in every reverse lookup. Changing a corporate identity takes a press release; changing every PTR record in a national access network takes a project nobody will fund.
LeaseLinecapitalised in the middle of an otherwise lowercase scheme is the kind of detail that dates a naming convention precisely. Someone typed it by hand, once, and every leased circuit since has inherited the capital L.

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.
