sonicwall dynamic address object

I've never seen this before, but our sonicwall NSA 4600 created dynamic address objects automatically.

I look at the time under system status for Last Modified, and these objects were created after the time shown for this. (I knew I didnt create them, but just to make sure)

This is what the log shows with message 'added host entry to dynamic address object'

Object=*.servicebus.windows.net

FQDN=adhsprodsyncwus.servicebus.windows.net;

TTL=23; Host=23.99.80.186

Object=*.servicebus.windows.net

FQDN=production-fantasy-nfl-com.servicebus.windows.net;

TTL=25; Host=23.100.43.151

when I look at the address objects I can see 2 new entries

*.msapproxy.net address properties: unresolved

*servicebus.windows.net address properties: host: 65.55.54.16 TTL3599

I am also seeing in the log 'failed to resolve dynamic address object'

Object=*.msappproxy.net...
