Title: Add fe80::1 to list of loopback addresses.

On my Mac, the loopback interface is configured (via `/etc/hosts`, out of the box) to have both a link-local and a node-local loopback address, with the link-local address taking precedence:

```
lo0: flags=8049 mtu 16384
options=3
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
inet 127.0.0.1 netmask 0xff000000
inet6 ::1 prefixlen 128
```

That obviously results in a `REMOTE_ADDR` of "fe80::1" rather than just "::1".
