Re: CNAME as an alias to a TXT record
Many thanks for all the responses. For the sake of completeness I am just reporting that every thing is working as expected.

Re: CNAME as an alias to a TXT record
Hi Reindl, Thanks for your response. no matter which record type a CNAME will match and that is the simple reason that you can't have A/MX records with the same name MX mail.example-com CNAME mail.example.com TXT whatever.example.com CNAME whatever.example.com yes, I understand that I can't have them in the same zone (ie in the same domain name). but not trying that here. I want the CNAME for firstdomain.com to point to a TXT record at seconddomain.com in both cases you need to chose because a CNAME with the same NAME is a conflicting configuration which is not possible or redundant which don't make sense ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
CNAME as an alias to a TXT record
Hi, I am wondering if it is possible to create a CNAME in one zone to resolve as a TXT record in another zone. Can't find anything that says it will work, but can't find any thing that says it won't, either. For example, I have added in the zone file for dom1: _acme-challenge CNAME _acme-challenge.dom2.com. and then in zone file for dom2: _acme-challenge TXT "thisismytextvalue" Then, and more or less as expected, the following dig command fails to return a record. dig -t TXT _acme-challenge.dom1.com Is there a way to get the dig command to return the TXT value for dom2?
