Return the host IPv6 address.
ipv6_address host_ipv6_address() const;
If the host type is host_type::ipv6
, this function returns the
address as a value of type ipv6_address
. Otherwise, if the
host type is not an IPv6 address, it returns a default-constructed value
which is equal to the unspecified address "0:0:0:0:0:0:0:0".
assert( url_view( "ftp://[::1]/" ).host_ipv6_address() == ipv6_address( "::1" ) );
Constant.
Throws nothing.
