You should not stop inetd.

inetd is used to spawn other daemons as needed (based on the config of /etc/inetd.conf). Prior to introduction of inetd one had to start all daemons and leave them running all the time. Just configure inetd.conf to only start those daemons you want to be able to access on demand rather than have running all the time. (For example on secure systems you generally want things like telnet, ftpd, rsh turned off in inetd and then use ssh/scp/sftp instead.)

DNS typically is run with BIND using the daemon, named, which should run all the time for a DNS server so should not be in inetd.

Some packages give you a choice as to whether to leave the daemon up all the time or to run it from inetd. Since it varies there is no one size fits all answer to your question but the key points in my response are:

Leave inetd on but disable unnecessary services in inetd.conf.
Run named as daemon from the BIND configuration (assuming your DNS is BIND and not something odd).

inetd is mostly used to spawn older programs such as telnet. You should not need inetd.
