About this network

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.net for broadband, ip-159-64.tricom.net for general assignments, and LeaseLine-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.
• LeaseLine capitalised 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.
