Allocating sub-domain names instead of IP Addresses to OpenVZ machines?

[todx]

I was just wondering if something like this is possible in ISPConfig3?

Lets say I run out of IP addresses and I need to create a virtual machine. Is it possible to create a sub-domain or a domain that would link to that server? ^^

-- within ISPConfig3 of course --

A virtual machine needs always a IP address, it can not runs with a subdomain. Thats not ispconfig soecific, its a requirement for virtual machines in general.
