.i2p is a pseudo-top-level domain which is only valid within I2P overlay network scope.Actually, .i2p names are resolved by browser by submitting request to a proxy program known as EeeProxy which will actually resolve nave to a I2P peer key and will handle actual data transfers over I2P network while all this remains transparent to browser.For more details on how his technique works, consider reading I2P article.
