Note:
The `SIOCSIFADDR` and `SIOCDIFADDR` uses different params for `AF_INET` and `AF_INET6` (`struct ifreq` vs `struct in6_ifreq`) as defined by https://man7.org/linux/man-pages/man7/netdevice.7.html

In dns_add_nameserver, the dns_check_nameserver is comparing addresses
with addrlen = sizeof(struct sockaddr_in) for IPv4 addresses, so the
trailing sin_zero field should be 0, otherwise it may fail to figure out
same nameserver address.
