That would be pretty difficult if not nearly impossible to do. These
are sub-domains which are part of a larger domain and they are usually
resolved and routed internally by DNS or web servers on the domain
owner's network, the domain itself is resolved by your ISP's DNS server
or by another bonafide DNS server. Domain hierarchy is read and
resolved from right to left.

So, sub.domain.com is resolved to domain.com by the the DNS server and
..sub is usully resolved internally at the domain.com server. See here
