BigDB.dat: Configsync.PeerIpaddr : No longer used in v11.6?

I have just found that the "[Configsync.PeerIpaddr]" section in the BigDB.dat contains an IP address that is different from what I get from:

 tmsh list /cm device my_device_name configsync-ip

, and it does not get overwritten by changes done via the Configuration Utility. It seems that this variable is no longer used in v11.6.x. Can anybody confirm this?
