Hi James,
In relation to tests I have done so far, also if they are at an early stage, they seems good

Can I ask some example of flaw that you have encountered so far?
At least I will be aware of it

I can’t answer this particular question but a fair argument could be made that it’s up to your application to do checking like that.

I experimented with the API quite a bit and eventually had to give up on it. It seems to be very early in its development and has some flaws. Given how easy it is to simply create and modify records in the database, I suggest you just go that route.

Good morning,
I was doing a bit of test in relation to PowerDNS API

I have created a CNAME “ciao8.rainbow.com<http://ciao8.rainbow.com/>” using API

After that I tried to create an A record with the same name “ciao8.rainbow.com<http://ciao8.rainbow.com/>” and the API allowed me to do so

Is this a wanted behaviour?
By RFC shouldn’t this be not allowed because

“"A CNAME record is not allowed to coexist with any other data."”

Any idea?

If you have already answered to a similar question could you give me the link that point to it please?
I have tried to have a look in the archive of this mailing list but I couldn’t find anything

Thanks in advance
