Custom DNS Suffixes

Hi All,

How do I add a simple DNS suffix such as a wildcard "*.ldn" or even "ldn" to custom dns suffixes?

I can add suffixes such as "mydomain.local" etc but not ldn on its own I have to manually add the search suffix for it to accept ldn

set-vmhostnetwork $vmHostNetworkInfo -hostname $esxhostname -SearchDomain "mydomain.local","MYDOMAIN.LOCAL","ldn"

is there a way to do this
