Residential APNIC Cable/DSL/ISP
Summary
Telecommunications Services of Trinidad and Tobago
isp legacy
The network of TSTT, the incumbent telecommunications operator of Trinidad and Tobago, which markets its consumer services under the bmobile brand.
What it's used for
- Consumer and business internet access nationwide: fixed broadband, fixed-wireless LTE, and mobile data.
- Roughly 297,000 IPv4 addresses, making this by a wide margin the largest network registered in the country.
Notable
- An eyeball network. Most of the space behind this AS terminates on end-user subscribers rather than on servers, which is what you would expect from a national incumbent carrier.
- The AS is registered through LACNIC rather than ARIN, following the transfer of Caribbean and Latin American records to the regional registry.
Interesting
- The TSTT group also operates Amplia, the fibre broadband and television provider formerly known as Massy Communications, so the incumbent owns both the legacy national footprint and a challenger-brand fibre network.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,775 prefixes, as published 2026-10-11. 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.
