Notice that the way you describe you do NOT "block" any domain, you just make sure that the name associated with the domain cannot be reliably translated into an IP-address any more. This is more like painting over a certain name in the telephone book with a black marker: you cannot look up the name and its associated number any more, but everybody who knows the telephone number (or has other means to find it out) could still call it.
I hope this helps.

mkfset(8) System Manager's Manual mkfset(8)
NAME
mkfset - Create a fileset in an existing AdvFS file domain
SYNOPSIS
/sbin/mkfset domain fileset
OPERANDS
Specifies the name of an existing AdvFS file domain. Specifies the name of the fileset to be created in the specified file domain.
DESCRIPTION
The mkfset command creates an AdvFS fileset within an existing file domain. You must create at least one fileset per file domain; however,
you can create multiple filesets within a file domain. You can mount and unmount each fileset independently of the other filesets in the
file domain. You can assign fileset quotas (block and file usage limits) to filesets.
Use the following commands to manipulate filesets: Displays the filesets associated with a domain. Removes a fileset (and all of its
files) from the file domain. Assigns a new name to an existing fileset. Changes fileset attributes; specifically fileset quotas.
For more information, see the reference pages for each command.
RESTRICTIONS
You must be the root user to use this utility.
Each fileset within a domain must have a unique name of up to 31 characters. All whitespace characters (tab, new line, space and so on)
and the / # : * ? characters are invalid for fileset names.
EXAMPLE
The following example creates two filesets, credit_fs and debit_fs, within an existing domain called accounts_dmn. # mkfset accounts_dmn
credit_fs # mkfset accounts_dmn debit_fs To mount the newly created credit_fs fileset on the /mnt/credit directory, enter: # mount -t advfs
accounts_dmn#credit_fs /mnt/credit You can add filesets to the /etc/fstab file in the same manner that you add any file system. Once added,
filesets are mounted each time you reboot the system and fileset quotas are enabled. For example, to automatically mount the credit_fs
fileset, add the following line to your fstab file:
accounts_dmn#credit_fs /mnt/credit advfs rq, userquota, groupquota
