Here is an example that an NIC has only link local address for IPv6.
```
$ ipaddr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
3: eth0@if18692: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1460 qdisc noqueue
link/ether 1a:5e:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
inet 10.xxx.xxx.xxx/24 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::xxxx:xxxx:xxxx:xxxx/64 scope link
valid_lft forever preferred_lft forever
```
If the NICs have only local or link local addresses, We should not send IPv6 DNS queris.
Modification:
- Ignore link-local IPv6 addresses which may exist even on a machine without IPv6 network.
Result:
- `DnsNameResolver` does not send DNS queries for AAAA when IPv6 is not available.
