# Looking Glasses

This is the list of **looking glasses** available for the dn42 network.  Some only display BGP information, while some others allow interactive queries (traceroute, details of a route, BGP-map visualisation, etc).

When a looking glass is described as `IPv4` or `IPv6`, it refers to the information displayed (or queried) by the looking glass, not to the reachability of the looking glass service itself.

## Reachable from the Internet & dn42
