When navigating to the Blackbaud.com downloads page, the version of Blackbaud NetCommunity that shows is 184.108.40.206. If your Blackbaud NetCommunity website is hosted by Blackbaud, the installed version may show as 220.127.116.11.
The fix for the issue described in the article only requires the RE plugin to be upgraded to version 18.104.22.168. As such, the NetCommunity website itself was not updated. The download is available for split hosted clients to upgrade REWS and their plugins. In this scenario it is acceptable to have a version mismatch in which BBNC is on 22.214.171.124 and REWS is on 126.96.36.199.
