Question: Currently on Security.SE the [domain](https://security.stackexchange.com/questions/tagged/domain "show questions tagged 'domain'") tag is being widely used as a synonym for both [dns](https://security.stackexchange.com/questions/tagged/dns "show questions tagged 'dns'") and [active-directory](https://security.stackexchange.com/questions/tagged/active-directory "show questions tagged 'active-directory'"). 

Is there someway this can be cleaned up, or clarified? Alternately, am I making much ado about nothing?

Answer: 
Yeah, that's worth creating [dns-domain](https://security.stackexchange.com/questions/tagged/dns-domain "show questions tagged 'dns-domain'") and [windows-domain](https://security.stackexchange.com/questions/tagged/windows-domain "show questions tagged 'windows-domain'"), then blacklisting [domain](https://security.stackexchange.com/questions/tagged/domain "show questions tagged 'domain'") after we reorg those questions.
I suggest we use [dns](https://security.stackexchange.com/questions/tagged/dns "show questions tagged 'dns'") and [active-directory](https://security.stackexchange.com/questions/tagged/active-directory "show questions tagged 'active-directory'") as our two tags, and blacklist [domain](https://security.stackexchange.com/questions/tagged/domain "show questions tagged 'domain'") (perhaps with a tag wiki that recommends using [dns](https://security.stackexchange.com/questions/tagged/dns "show questions tagged 'dns'") or [active-directory](https://security.stackexchange.com/questions/tagged/active-directory "show questions tagged 'active-directory'"), depending).

Like AviD says, `dns-domain` seems redundant; `dns` seems fine.

Like Luc says, I don't think we need both `windows-domain` and `active-directory`. We could have `windows-domain` be a synonym for `active-directory`, I suppose, but that seems unnecessary.
