Typically the reason why you want to force which nameserver to ask is when you want to ask multiple different nameservers.
Using GNU Parallel you can do:
parallel host {1} {2} :::: hostlist.txt ::: 8.8.8.8 1.1.1.1
To see the results use --tag:
parallel --tag host {1} {2} :::: hostlist.txt ::: 8.8.8.8 1.1.1.1
Often your hostlist is quite big and by adding -j100 you can resolve 100 hosts in parallel.
