Private Attributes | |
std::string | hostname |
The hostname. | |
int | address_length |
The length of the resolved address. | |
sockaddr_storage | address |
The resolved address. | |
bool | resolved |

Wrapper for (un)resolved network addresses; there's no reason to transform a numeric IP to a string and then back again to pass it to functions.
It furthermore allows easier delaying of the hostname lookup.
