[public-dns-discuss] Incorrect cached results for ddns.net address Showing



Hi Support,
Getting some unusual results from 8.8.8.8 for our subdomain supportcentre.ddns.net
This is occurring across Australia, on around 1400 windows workstations

The correct IP address that is currently set on the Name servers is 220.233.202.9
This has been updated from 115.70.133.218 at least 4 days ago and has been present since.
I went through the flush cache link for the public DNS.

C:\Users\Mitch>nslookup -q=a -debug supportcentre.ddns.net 8.8.8.8
