I own a domain, let's say example.com I want that domain to lead to my ddns hostname, so on my DNS I added CNAME record: Alias * name dynamic-dns.org. That works perfectly.
Recently, I run into the need of having subdomain leading to another machine, so I added record "A" Name: foo Address: ip address of that machine. But that configuration doesn't work. My guess is that there shouldn't be any wildcard in cname record... but what else should be there?
1Subdomain has an "A" record? Why not use a "CNAME"? Target server has to be configured to recognize requests for "A" records. Which is why you should use CNAME, and then you don't have to worry about the IP changing on the target server. – Logman – 2013-08-01T21:27:23.457
Further, to prevent interesting problems and aggrevation, I generally never use wildcard DNS records. – mdpc – 2013-08-01T21:56:37.383
BTW, One CAN have multiple A named records for a designated IP number. – mdpc – 2013-08-01T21:57:04.010
