Dig for link-local

This is really awesome!
It works for me, my own glibc-2.3 is able to resolve the domain name and fetch me an ip address.
I had re'd that scope concept in link-local, but was not sure about using it in resolv.conf.
Thank you all for replying.
God bless you!!

Have you specified the "scope" in the link-local address i.e.
...or similar? Link-locals cannot be used without a scope. For example:
# dig @fe80::blah www.ic.ac.uk
; <<>> DiG 9.8.3-P4-RedHat-9.8.3-5.P4.el5 <<>> @fe80::blah www.ic.ac.uk ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached
...fails, but then this:
# dig @fe80::blah%eth0 www.ic.ac.uk
; <<>> DiG 9.8.3-P4-RedHat-9.8.3-5.P4.el5 <<>> @fe80::blah%eth0 www.ic.ac.uk ; (1 server found) ;; global options: +cmd ;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 32643 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 7
...works. This is basic IPv6, and not dig-specific.
