This page gives the list of Autonomous System Numbers (ASNs) delegated in Trinidad and Tobago (TT) by Regional Internet Registries (RIRs), according to RIRs delegations files: AFRINIC (Africa), APNIC (Asia-Pacific), ARIN (North America), LACNIC (Latin America and the Caribbean) and RIPE NCC (Europe, the Middle East and parts of Central Asia).

The status of each delegation is indicated as "Allocated" or "Assigned":

• Allocated delegations are ranges distributed by RIRs to LIRs for the purpose of subsequent distribution to End Users.
• Assigned delegations are ranges distributed by RIRs to LIRs or End Users for their own use and not supposed to be redistributed.

Other possible values for the status are "Available" and "Reserved". Available and reserved ranges are not included in these tables.

Column "Date" gives the date of allocation or assignment for each range in the format "YYYY-MM-DD".

The link on an ASN opens the RIR Whois page corresponding to this ASN in a new window (RIR website).
In the case of AFRINIC RIR, you need to first copy the ASN and then paste it into the Whois page search field.
