So you've configured '123.123.123.123.mylab' to be resolved to an IP of 
'123.123.123.123'.

I wonder:
If your intention is to ssh into your clients by IP address anyway, then 
why would you want to involve DNS here at all?


Instead of referencing the host by name, e.g.

ssh 123.123.123.123.mylab

is there a reason why using the IP address directly, e.g.

ssh 123.123.123.123

would not work for you?
