Prevent unwanted DNS A record
Hi Falko and Till

I found unwanted behaviour if CNAME record is created .. for example:

I have domain with many subdomains ( , , etc. ..) which pointing to few different servers (, .. so I decided make it as CNAME .. so I have:

A records:
123.456.789.101 -
123.456.789.102 -
123.456.789.103 -

CNAME records:
first -
seccond -
dog -
cat -
animals -


In this case is necessary uncheck "Create DNS record" in web setting and everything is ok .. but if somebody unfortunately check this field (yes it is possible .. I know it :rolleyes: ) for than ispconfig create A record for it. Now we have A record for and CNAME record too without any warning. Finnaly DNS server cannot handle and ends with SERVFAIL.

# host
Host not found: 2(SERVFAIL)

So what I want to say .. :)

It would be nice if somebody try to check "Create DNS record" for subdomain with CNAME record than ispconfig tell him about this problem.

Thanks for attention :)
