Good point.  We would probably want to fix socket to support this before adding support to ipaddr.  I think it is reasonable for socket to support it, as tools dealing with IPv6 should handle zone identifiers. I tried ping6 and traceroute6:

```
$ ping6 fe80::1%lo0
PING fe80::1%lo0 (fe80::1%lo0): 56 data bytes
64 bytes from fe80::1%lo0: icmp_seq=0 hlim=64 time=0.630 ms
$ traceroute6 fe80::1
traceroute6 to fe80::1%lo (fe80::1%lo0), 64 hops max, 60 byte packets
 1  fe80::1%lo0 (fe80::1%lo0)  0.162 ms  0.098 ms  0.091 ms
```

Ignoring the zone identifier is not valid:

```
$ ping6 fe80::1
PING fe80::1 (fe80::1): 56 data bytes
ping6: sendmsg: Network is unreachable
$ traceroute6 fe80::1
traceroute6 to fe80::1 (fe80::1), 64 hops max, 60 byte packets
traceroute6: sendto: Network is unreachable
```

----------------------------------------
Feature #10911: IPAddr.new should ignore zone identifiers
https://bugs.ruby-lang.org/issues/10911#change-82406

* Author: postmodern (Hal Brodigan)

* Assignee: knu (Akinori MUSHA)
* Target version: 
----------------------------------------
Link local IPv6 addresses may have a zone identifier suffix:

    fe80::1%lo0

IPAddr.new currently does not ignore the zone identifier and raises IPAddr::InvalidAddressError.
