dig @ipv6-address
Hello, I'm trying to use dig version 9.10.3 to test my local DNS server which listens on IPv6 only. I only get an error when running dig: > $ dig @2a01:488:66:1000:53a9:2dde:0:1 cweiske.de > couldn't get address for '2a01:488:66:1000:53a:53': not found So how can I specify an IPv6 address in the "@" server parameter? I found the same question in the mailing list archive of 2013; https://lists.isc.org/mailman/htdig/bind-users/2013-August/091479.html The solution there was to not only pass the IPv6 address, but also the network interface name. This unfortunately does not seem to work anymore: > $ ifconfig venet0 > venet0: flags=211 mtu 1500 > inet 127.0.0.1 netmask 255.255.255.255 broadcast 0.0.0.0 destination > 127.0.0.1 > inet6 ::2 prefixlen 128 scopeid 0x80 > inet6 2a01:488:66:1000:53a9:2dde:0:1 prefixlen 128 scopeid > 0x0 > > $ dig @2a01:488:66:1000:53a:53%venet0 cweiske.de > dig: couldn't get address for '2a01:488:66:1000:53a:53%venet0': not > found What works is adding an IPv6-only entry to /etc/hosts and then using that as hostname in @: > $ grep ahso3- /etc/hosts > 83.169.45.222 ahso3-ipv4 > 2a01:488:66:1000:53a9:2dde:0:1 ahso3-ipv6 > > $ dig @ahso3-ipv6 +short cweiske.de > 2a01:488:66:1000:523:f116:0:1 But this is just a workaround. How can I specify an IPv6 address in the @ server parameter of dig? -- Regards/Mit freundlichen Grüßen Christian Weiske -=≡ Geeking around in the name of science since 1982 ≡=- ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

And the error doesn't match the command given. I suspect that your actual 'dig' command was 'dig @2a01:488:66:1000:53a:53 cweiske.de', which will reproduce the error. '2a01:488:66:1000:53a:53' is not an IPv6 address. You are missing a :: or a couple of words. (There should be 8 16-bit words delimited by ':', or a single '::' ellipsis to represent a run of zeroes.) Since it doesn't parse as an IPv6 address, dig (probably getaddrinfo()) tried to translate the string as a hostname. Hence the error. It's really not in anyone's interest when people post obfuscated questions...

You are missing > a :: or a couple of words. (There should be 8 16-bit words delimited > by ':', or a single '::' ellipsis to represent a run of zeroes.) You are right, this was no full IPv6 address. I'm sorry for the noise, but I didn't see the difference in the two IP addresses. Otherwise I would not have subscribed to this list and written my lenghty mail. I scrolled back my terminal and now found where I got that partial address from: The output of "netstat -tulpen". The listening address is shortened there, which I did not know before: > Proto Recv-Q Send-Q Local Address Foreign Address > udp6 0 0 2a01:488:66:1000:53a:53 :::* From there I copied it and tried to "dig @" my domain, which failed as I wrote. Why there were different IPs in the command and the output of my first example .. I have no idea. I somehow mixed up my notices. Sorry again. -- Regards/Mit freundlichen Grüßen Christian Weiske -=≡ Geeking around in the name of science since 1982 ≡=- ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

The last : in the netstat output is separating the IP address from the port number -- :53 means it's listening on port 53, the standard DNS port. But it also seems like it's using its own form of abbreviation, since there aren't 8 hex fields before that. -- Barry Margolin Arlington, MA ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
