Return the host IPv4 address.
ipv4_address host_ipv4_address() const;
If the host type is host_type::ipv4
, this function returns the
address as a value of type ipv4_address
. Otherwise, if the
host type is not an IPv4 address, it returns a default-constructed value
which is equal to the unspecified address "0.0.0.0".
