Error: Expected 4 octets in '...an-IPv6-adress-is-shown-here...' about dnsupdate HOT 7 CLOSED

I think this is coming from the address provider. Are you using the default address provider (Web, which uses https://icanhazip.com/ by default)? If so, could you check that curl https://ipv4.icanhazip.com/ returns an IPv4 address? Make sure you run that command on the same machine you are running dnsupdate on.

from dnsupdate.

Yes I have almost everything on default, my config looks like this:

dns_services:
    - type: NSUpdate
      args:
          hostname: some_host_name
          secret_key: the_key
    - type: FreeDNS
      args:
          ipv4_key: the_v4_key
          ipv6_key: the_v6_key

Tonight, during the DSL reconnect, everything suddenly worked again. The update worked without errors.
I entered the command curl https://ipv4.icanhazip.com/ before and got an IPv4 address.
Yesterday, of course, I don't know, but there I had entered the command ip a and saw that the interface had both an IPv4 and an IPv6 address. I have dual stack and so an official IPv4 address as well as IPv6 address.

from dnsupdate.

dnsupdate should work fine with dual stack; that's actually part of the reason I wrote it. ipv4.icanhazip.com should only resolve to an IPv4 address, and therefore show your IPv4 address even if you have an IPv6 address as well. Off the top of my head, I can't think of a reason for that error other than ipv4.icanhazip.com somehow returning a IPv6 address.

If it happens again, run curl https://ipv4.icanhazip.com/ and drill ipv4.icanhazip.com (or dig if that is available on your system instead) to try to see what is happening.

from dnsupdate.

Yes, very well possible that it was exactly like that.
Because the error occurred only 5 days and disappeared as suddenly as it had come.
Thanks for the reply :-)

from dnsupdate.

The error just appears again.
I used curl and noticed that when I use curl -6 https://ipv4.icanhazip.com/ I get an IPv6 address and
when I use curl -4 https://ipv6.icanhazip.com/ I get an IPv4 address.
Is it possible to force the IP version in Python when doing these queries?

from dnsupdate.

There is an open issue about this: major/icanhaz#31. I'll look into workarounds, but unfortunately there doesn't seem to be a non-hacky way to force requests to use a particular protocol.

from dnsupdate.

This should be fixed in master.
