Fetching process fails when device is reached via an ipv6 address

[ocl80]

Hello,
I'm relatively new to Oxidized (and Ruby), but I have it working nicely except for devices reached via IPv6.
A device whose name resolves to an IPv6 address looks normal until the job is added to the queue then generates the output below in the debug log:

D, [2023-08-11T11:27:42.206040 #16344] DEBUG -- : resolving DNS for ip6device.lab...
D, [2023-08-11T11:27:42.206054 #16344] DEBUG -- : IPADDR 

then

D, [2023-08-11T11:27:54.451830 #16344] DEBUG -- : lib/oxidized/worker.rb: Added Cisco Lab/ip6device.lab to the job queue

W, [2023-08-11T11:27:55.453586 #16344]  WARN -- : Cisco Lab/ip6device.lab status fail, retry attempt 1

I see the same result whether resolving the hostname, or declaring the IPv6 address explicitly in router.db.
I'm not seeing any clues as to specifically what is failing. Is it expected the Oxidized cannot reach devices using ipv6 ?

After some further some further testing, I have understood that the problem occurs because I have set the delimiter for the CSV input to be not the default colon : so that I could declare ipv6 addresses (including colons) in the router.db (in my case I set the delimited to be a comma).

With delimiter for CSV input set to comma, the following check in node.rb fails and the input is skipped:

# don't try input if model is missing config block, we may need strong config to class_name map
cfg_name = input.to_s.split('::').last.downcase
next unless @model.cfg[cfg_name] && (not @model.cfg[cfg_name].empty?)

I have not yet fully understood what this check is doing, but if either comment it out, or set delimiter to default colon : and use DNS to find the connection address, oxidized successfully connects to the device and collects its config.

I am now looking for a good way to be able to use an explicitly declared ipv6 address in router.db.

[ocl80]

I suspect I made a mistake in the config initially, with the delimiter pattern configured.
With a more specific delimiter in the config file of /::*/ and explicitly declared ipv6 address in router.db, I can fetch configs OK.
So I'm closing the issue.
