BT Internet Connect Global: Looking Glass

Welcome to the BT Looking Glass site where we allow you restricted access to live network information from a subset of access and peering routers on our AS5400 and AS3300 networks.

The following table lists the requests that we currently allow you to perform on our routers. All these queries will require you to input some further information. This extra information may be an IP address or DNS name, and you may be required to choose one of the routers on the BT core network on which you would like us to execute your request.

Please choose a tool from the list below:
Ping Traceroute
Nslookup Dig
BGP network  

Please be aware that the use of these tools will be strictly monitored by BT personnel. Please see the BT Acceptable Use Policy for further details.
