SQL Availability Group Network On a SQL Availability Group what IP/network carries the workload of moving changes to the secondary replica and how do you find this network?
In my understanding of your question:


to check where network packet will go look at results of ROUTE PRINT (Hit [Windows]+[R], type CMD, hit [Enter]). Read article on Technet.
with TRACERT x.x.x.x (where x.x.x.x is your secondary replica servers IP address) you will see a route that's packet travels.
