Improve cut on IPv6 addresses

[hubertqc]

Make cut retrieve the complete IPv6 address

Hi @hubertqc, thanks for submitting a PR to fix this! A couple of things with respect to the patch description and subject line:

• Make sure you "sign your work", there is a good description of what is needed in the CONTRIBUTING.md file.
• Try to use the "(sub-area): (summary)" format for the patch subject line. For example, for this patch I might use "netlabel-config: fix IPv4 address parsing in nlbl_reset_unlbl()".

Sometimes it can be helpful to look at previous commits which are now in-tree as a source of examples; the top of the current main branch, commit https://github.com/netlabel/netlabel_tools/commit/b9776c02c65d5d7bd2353c095e3d7f8702ab18f2, is a decent example.

Hopefully this helps, but if you have any questions don't hesitate to ask.

Thanks!

Hi @pcmoore ,

Thank you very much for your guidance and your patience.

I've just amended the commit message to comply with your recommendations regarding both signing the commit and formatting the commit label.

Thanks.
