Looking glass
The public looking glass is lg.templass.com. It probes from Templass in Frankfurt.
How to use it
- Open lg.templass.com. The heading is Looking glass.
- Enter an IPv4, IPv6, or hostname in the target field. Placeholder example:
1.1.1.1 / 2606:4700:4700::1111 / example.com. - Click Ping.
Use it to confirm reachability from the Templass edge, not as a substitute for your own traceroute after cutover.
When it helps
- After GRE or Cross-Connect bring-up, ping a public resolver and then your protected prefix from an off-net host. The looking glass is the Frankfurt vantage point.
- When routing looks wrong, compare an off-net traceroute with a probe from FR5.
- Registry and ASN context lives on AS208743. The looking glass does not replace RIPE.
Looking-glass availability is operational. It is not a separate SLA unless your quote says so. Access may present a challenge before the form.
