Pretend a CNAME has a TTL of 1 hour that points to an A record with a TTL of 1 minute.

Will someone who looks up this CNAME record have the entire result cached for 1 hour, or will it will keep having to lookup the A record every 1 minute?

I can't find the answer to this anywhere and don't really have the know-how to manually test it.

Can a CNAME be a hostname

as seen on Server Fault - Search for 'Server Fault'
This is bit of a theological question, but nonetheless... So, a server has a hostname, let's say the fqdn is hostname.example.com (to be really precise about what I mean, this is the name that is set in /etc/sysconfig/network). The very same server has multiple interfaces on different subnets. Let's… >>> More
