I setup a rpi 3 b+ to run wireguard and would like to setup dynamic DNS to update my cloudflare DNS.  
I just put on a new image (armv7 32-bit)

I noticed dietpi comes with a built in dynamic DNS client. I notice a “custom URL” option that can be specified. Is this something that can be used with cloudflare?

Alterntaively, I tried installing ddclient (apt-get install ddclient libio-socket-ssl-perl) but I get this error:

```nohighlight
Can't load '/usr/lib/arm-linux-gnueabihf/perl/5.32/auto/Sys/Hostname/Hostname.so' for module Sys::Hostname: /usr/lib/arm-linux-gnueabihf/perl/5.32/auto/Sys/Hostname/Hostname.so: invalid ELF header at /usr/lib/arm-linux-gnueabihf/perl-base/XSLoader.pm line 93.
 at /usr/lib/arm-linux-gnueabihf/perl/5.32/Sys/Hostname.pm line 24.

Compilation failed in require at /usr/share/perl5/IO/Socket/SSL/PublicSuffix.pm line 165.
BEGIN failed--compilation aborted.

```

It doesn’t matter though since I found that ddclient [no longer works with cloudflare](https://github.com/ddclient/ddclient/issues/361) in it’s latest release (over a year ago).  
If the built-in dietpi DDNS client doesn’t support cloudflare and ddclient doesnt either, can anyone suggest an alternative?

it should be possible to use the custom option inside dietpi-ddns, if you have an update link to update your DDNS. You could simply try it out.

usually there should be some FAQ on Cloudflare website on how to update the DDNS from external.
