To do what? Those queries should already be producing indexscan plans.
If you're not getting the expected answers, there is something that
needs to be fixed, not papered over.
Please try
create index inet_idx1 on inet_tbl(i);
set enable_seqscan to off;
explain select * from inet_tbl where i<<'192.168.1.0/24'::cidr;
