Abutalib Shaikh:
is there is any way to restrict access on the basics of IP address?
Not in Liferay - but if you configure e.g. an Apache Httpd in front of Tomcat (assuming this is what you're using), you can easily filter different URLs for different IP addresses. Of course there are numerous other options, but all of them are somewhat outside of Liferay's realm
Abutalib Shaikh:
how we configure banned IP list ?
depending on the solution you choose.
You might want to let us know what business problem you're solving with this - that might make it easier to recommend (for or against) one of the possible solutions.
