DNS Subdomains to different IPs (A vs CNAME records?)

November 6, 2013 30.6k views
Hello, I've setup DNS to my droplet, with a wildcard CNAME, as explained in the tutorial ( https://www.digitalocean.com/community/articles/how-to-set-up-a-host-name-with-digitalocean ) and it works fine. Now I'd like to connect a specific sub-domain to a different Droplet/IP. Example: current setup: server.com => 1.2.3.4 www.server.com => 1.2.3.4 xxx.server.com => 1.2.3.4 foobar.server.com => 1.2.3.4 What I'd like to add: work.server.com => 5.6.7.8 Based on simple google search, adding another "A" record pointing to "5.6.7.8" should "just work", and take priority over the wildcard CNAME (which points "*" => "@" => 1.2.3.4). However, this didn't work, or I have not configured it correctly in the DigitalOcean's DNS page. My "zone file" has this (IPs changed for brevity): === $TTL 1800 @ IN SOA NS1.DIGITALOCEAN.COM. hostmaster.SERVER.org. ( 1383653276 ; last update: 2013-11-05 12:07:56 UTC 3600 ; refresh 900 ; retry 1209600 ; expire 1800 ; ttl ) IN NS NS1.DIGITALOCEAN.COM. NS NS2.DIGITALOCEAN.COM. NS NS3.DIGITALOCEAN.COM. @ IN A 1.2.3.4 * CNAME @ work. IN A 5.6.7.8 === However, "ping work.server.com" still gives 1.2.3.4 instead of 5.6.7.8 . What am I doing wrong? Thanks! - G

Pay particular attention to formatting, either:
work    A    5.6.7.8

or
work.server.com.    A    5.6.7.8

should suffice. Notice the trialing dot in the second example. In the first example, DigitalOcean's DNS Manager will automatically append server.com..
