Hi all,
Wget 1.11.4 does not support IPv6 link local addresses. Addresses with a
zone identifier are being rejected with "Invalid IPv6 numeric address".
e.g.:
$ wget http://[fe80::1%25eth0]/
http://[fe80::1%25eth0]/: Invalid IPv6 numeric address.
"%25" is encoded for '%', the delimiter for the zone identifier.
Such an URL gets rejected by is_valid_ipv6_address() in host.c. This
function only accepts hex digits, ':' and '.' as valid charactes in an
IPv6 address. The zone delimeter and the zone identifier are regarded as
invalid.
RFC 4007 sais:
An implementation SHOULD support at least numerical indices that are
non-negative decimal integers as <zone_id>.
Please consider extending Wget to support link local addresses as well.
Regards,
Fabian
