Looking Glass

Our Looking Glass tool provides you with information on network routing and efficiency. Traceroute lets you follow a packet through the network to a specific destination. It shows the domain, IP address and the roundtrip packet times. Ping shows you whether a device with a valid IP address can return packets sent to it by a specified server.

Parameter

The parameter must be a valid destination. Destination means an IPv4/IPv6 address or a subnet. Masks are also accepted as part of a valid IPv4/IPv6 address.
RFC1918 addresses, IPv6 starting with FD or FC, and IPv4 reserved ranges (0.0.0.0/8, 169.254.0.0/16, 192.0.2.0/24 and 224.0.0.0/4) may be refused.
Please note that some routers always need a mask to be given when looking for an IPv6 address.

Example of valid arguments:
  • 8.8.8.8
  • 8.8.4.0/24
  • 2001:db8:1337::42
  • 2001:db8::/32
