Canonically Unique Host

The Basics

A Canonically-unique host is a FQDN that will canonically resolve to a designated address or set of addresses. Not to be confused with a locally-unique-host.

In-depth information

A Canonically-unique host is defined by remote authoritative sources; usually through DNS. When resolving a peer’s hostname, you will most likely use an external source for resolution unless you have the following implemented:

• a database file similar to a [hosts file] (https://en.wikipedia.org/wiki/Hosts_(file))
• an internal-network resolver (which eventually pulls from external sources)

Notes

• Haven primarily uses @canonically-unique-host resolution while I2P only uses locally-unique-host resolution.
