I can see this is resolved, just my 2c :

98.136.0.0 - 98.136.196.255 (wow) is actually :
98.136.0.0 - 98.139.255.255 (WOW - big one)

My recommendation actually is to us ~all temporary, keep it for some time
until you find what really need, then make better definition and revert to
-all

Also, if you are using huge block because of big ISP dynamic IP range, I
am almost sure you can made it smaller, or use reverse like I did (with
some dynamic dns). Keep in mind that IP4 should be on line start and
something ugly like I did at end, I have dynamic IP, check mine as
example. I mean : mine is ugly because of dynamic dns and 60 sec :)

Dejan
