Catalog zones

[udf2457]

Would be great if you had support for creating catalog zones.

In keeping with the dnscontrol concept it would be nice to have it all in one tool instead of generating in dnscontrol and then a hacky bash script to generate the catalog.

Hi there!

I wouldn't turn down a PR to add this kind of feature. However it isn't something I'd be able to implement. (My employer only funds me to implement features they use/need.)

I'd be glad to mentor you or anyone interested in implementing this.

Best,
Tom

Thanks @tlimoncelli Right now I have a lot on at $work and can't devote any time to anything else, but maybe one day.

Also my testing isn't going well with dnscontrol anyway, for example master in creds.json doesn't seem to work with the custom port, I get:

provider axfrddns Error: dial tcp <removed>:5353: connect: connection refused

But I don't see anyhing logged on the destination side, so I'm not convinced dnscontrol is actually doing anything and I don't see anything on the tcpdump either. Its not a firewall thing because a simple dig on the same port works without issues.

So at this stage I'm very tempted to go try octodns instead, even though I prefer supporting a go project instead of a python one. 😉

octodns is an excellent project. Years ago I had lunch with the maintainers. They were super cool!

Off the top of my head, here are some differences you might find relevant:

• That octodns uses YAML while DNSControl uses a JS-like language.
• DNSControl's axfrddns provider is "community supported" (the lower of 2 levels of support). octodns's support for axfrdns is described on their repo.
• octodns is better funded.
• octodns has plug-ins that are maintained in separate repos making it easier to expand.
• I prefer DNSControl's ability to make macros, variables, etc. (but, of course, I'm biased)
• And, as you mentioned, Go vs. Python.

But of course, do your own research. Bottom line: I don't think you can go wrong with either.
