Return the address as a string in dotted decimal format
templateStringToken::result_type to_string(StringToken&& token) const;
When called with no arguments, the return type is `std::string`. Otherwise, the return type and style of output is determined by which string token is passed.
assert( ipv4_address(0x01020304).to_string() == "1.2.3.4" );
Constant.
Strong guarantee. Calls to allocate may throw. String tokens may throw exceptions.
