kovri	Canonically-unique-host	A host that is canonically resolved to an address or set of addresses

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
• an internal-network resolver (which eventually pulls from external sources)

Notes

• Monero primarily uses @canonically-unique-host resolution while @I2P only uses @locally-unique-host resolution.
• @I2P's and @Kovri's self-assigned top-level domain is currently .i2p and @Kovri intends to only process/use the .i2p top-level domain
