III. Details

Inetd has an option
     -R rate ... default is 256 ...
... if more than 256 connections received in one minute [inetd] will
disable service for next 10 minutes ...
... IP address of attacker will never be logged.

IV. Workaround

-R 0 -s your_ad_can_be_here

I guess you are trying to say that xinetd is more configurable than inetd.
Yes, it is known that with inetd you need tcp_wrappers to log attack IPs.

Your cure is worse than the disease: rate limiting allows a DoS against the
service, no limit allows a DoS against the whole machine.
