Yes. According to https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwa47133, 22.214.171.124 is affected. Syntax is a little different on the CSC page as it is listed as 002.006(000.156) but I'd assume this is the same as "126.96.36.199".
My guess is yes. Anything on the 2.X version would be affected based on what I'm reading but please don't quote me on that. Although Cisco does a great job researching and communicating this information, I've seen many bugs impact IOS versions that are not listed in the 'affected releases' section. It is still too early to tell. I'm watching hourly to see if/when there are some updates to this one. Best of luck!
We have hotfix to fix log4j on the below version right ?
Version : 188.8.131.52
