Help with search query for non-reporting IP addresses?

Hi All,

I have a field name ip_address which has 50 IP values in it.  at every 5mins interval, I will receive the same values.

ip_address

10.1.1.1
10.1.1.2
10.1.1.3
.
.
.
10.1.1.49
10.1.1.50

What are ways to list down the values which are not coming to splunk. Let's say 10.1.1.2 and 10.1.1.45 are not coming to splunk. Then I need those missing values to be listed in statistical way to create an alert for missing ip address. 

What are ways to achieve this.

Please help 🙂 Thanks in advance.

Finding something that is not there is not Splunk's strong suit.  See this blog entry for a good write-up on it.
