DNS Domain Name for SAP System

Hello everyone!

we are installing Solution manager 7.2 (on MSSQL 2012, Windows Server 2016) and were asked to enter the DNS Domain Name to install the ABAP stack via SWPM. I believe based on the research we've made that we still don't have a domain for our Solution Manger. ( I run ipconfig and have DNS suffix empty)

I would like to know what can we do in this case and if there are alternatives to put a random domain name for it and maybe change it later. I also wonder whether it is possible to skip this step and what consequences it has? if not what can we possibly do in this case.

Thanks A lot.
