Looks like there is a bug in line 542 in ddclient.in. The syntax of how the server URL is being set is different to all the other dynamic DNS services. To be precise there is one additional parameter. Instead of handing over the URL, the server variable receives the second "1" in the code below.
$globals{postscript} can now contain a full command string including
arguments. In order to facilitate this, the file executability check
(-x) has been modified such that the first substring up to the first
space (if it exists) is what is checked, rather than the whole string.
Example bodies I've seen:
```
0013
good 127.0.0.1
0
```
```
0013
nochg 127.0.0.1
0
```
```
007
nohost
0
```
Seems like the trailing zero was not there before as the code relied
on `pop`. Instead, we find the first line that matches `good`/`nochg`.
From doc in IO::Socket::IP in "IO::Socket::INET" INCOMPATIBILITES
section:
-----
The behaviour enabled by "MultiHomed" is in fact implemented by
"IO::Socket::IP" as it is required to correctly support searching for a
useable address from the results of the getaddrinfo(3) call. The
constructor will ignore the value of this argument, except if it is
defined but false. An exception is thrown in this case, because that
would request it disable the getaddrinfo(3) search behaviour in the
first place.
-----
Module IO::Socket::INET6 is deprecated.
There is common IO::Socket::IP module, which is working with ipv4 and
ipv6 in same way. There is backward compatibility with IO::Socket::INET6
This is no longer used since commit 6c951a0395 ("Add files via
upload"), which updated to the Cloudflare API v4. The new API does not
require any preprocessing of the domain name.
This will make it possible for the Debian package to fetch the list of
supported firewall/router devices and prompt the user to choose one
upon installation.
This will make it possible for the Debian package to fetch the list of

to choose one upon installation.
