Is it normal for a CMDB Connector for z/OS region to have an UDP port connection shown as open?

Environment

Release:
Component: CMDBCN

Resolution

If the region's /PARMS group SOCKETS (2nd screen) parm Domain Name Resolution--Use DNR Provided By

has value = SOLVE the UDP port connection is allocated and stays open.

those DNR servers communicate back to SOLVE DNR stats/paths/etc.
