Default sort 2 or more occurrences


Hi

I have an excel sheet that I use as a log for my firewall. I one column
I have all the IP addresses that have been log by the firewall. What i
want to do is to, in a new column, sort the IP's based on number of
occurrences and only listing those with 2 or more occurrences.

The closest I have come is in the attachment. The only problem with
that “solution” is that it cannot handle different IP’s with the same
number of occurrences.

I tried adding the IP’s as decimals to the occurrences but since an IP
can have 12 figures and more that 100 occurrences, i.e. 3 more figures,
and I had to add a trailing 0 to cope with blank cells I broke the 15
figures limit.

Any help would be great.

The excel file looks like this

A1:A12


123.123.123.123
123.123.123.123
123.123.123.123
123.321.321.321
321.321.321.321

123.123.321.321
123.123.321.321
321.321.321.321
123.123.123.321
1.1.1.5

Paste as arrayformula in B2 and drag to B12
{=LARGE(IF(COUNTIF($A$2:$A$12,$A$2:$A$12)=2,COUNT IF($A$2:$A$12,$A$2:$A$12)),SUM(B$1:B1)+1)}

Paste as arrayformula in C2 and drag to C12
{=INDEX($A$2:$A$12,MATCH(B2,COUNTIF($A$2:$A$12,$A$ 2:$A$12),0))}
