| Subject: | delv may send bogus queries when -4/-6 is used |
When -4 or -6 is specified on the command line along with an explicit
server address belonging to the disabled address family, delv will send
out bogus queries in an attempt to resolve the provided server "name".
To reproduce, put the following in /etc/resolv.conf:
search foo.bar
nameserver 127.0.0.1
and then run:
$ delv -4 @::1 isc.org
This will result in queries for "::1.foo.bar." and "::1." being sent to
127.0.0.1, as proved by the attached PCAP file.
Depending on host configuration, this issue might result in test traffic
being leaked when the digdelv system test is run.
