"Subdomain" after my website name

Question

Is there a way to dynamically create a kind of sub-domain that goes between my website domain and the .com?

For instance, www.onlinevet.com would be something like:

www.onlinevet.dog.com
www.onlinevet.cat.com

technically that would be a domain, not a subdomain... – Bename

No. You would have to own dog.com, cat.com, etc.. – Gourami

Answer 1

That's not possible as domains are processed from right to left in a hierarchical manner meaning that each domain is a subdomain of the domain immediately to it's right. To create a subdomain, it must appear to the left of your domain name. You could create

www.dog.onlinevet.com

as that would have a dog subdomian registered to onlinevet.com, but not

www.onlinevet.dog.com

as that would have a onlinevet subdomain registered to dog.com

Answer 2

As John Weldon says, you would be using separate domains. "dog.com" is it's own top-level domain, as is "cat.com". So you'd have to own the dog.com domain name and cat.com domain name to create your "onlinevet" subdomains for each of those.

You are absolutely right, but I am not going to ruin you exact 1k rep by opvoting you :p – Slipshod

@Jørn either that, or we would have to find three people to upvote, and three to downvote, to get him to 1024 :) – Implosive

Lol! I've been waiting for quite some time to get 1000+. I've got 1028 now, not quite 1024 but close ;o) I'll shoot for 2048. – Addition

Answer 3

No, only the other way around.

To do what you are requesting, you need to own the domain name "dog.com" and "cat.com".

A subdomain always come before your domain name: subdomain.domain.tld, for example horses.cats.com. You can create the subdomain 'horses', only if you own 'cats.com'.
