About this network

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.
