5.6.1.1. [Critical] DNS Tracking not supported with participants using SPDP2
DNS tracking was not supported for DomainParticipants using SPDP2. The DomainParticipant continued sending bootstrap announcements to the IP address of newly resolved hostnames, even if existing participants were using the IP address, resulting in excess traffic.
The DomainParticipant may have also failed to resume sending bootstrap announcements to the IP address that a hostname was resolved to once existing remote participants using that IP address lost liveliness. This caused a failure to discover new remote participants at those IP addresses.
DNS tracking is now supported when using SPDP2.
