Hostname for cache without dns based discovery

Hello,
can I use memcached without service discovery? We use ElastiCache on AWS.
I tried with host, service and addresses parameter, but it always tries to do a dns based service lookup. Even the dns+ prefix did not work.

Is it possible to put a static hostname without the need to manage srv records in dns?
