vRA DNS requests flood
Knowledge Transfer: Today, I finally figured out why my vRA system was killing my PiHole. vRA wanted to lookup itself in IPv6 form. I do not run IPv6 in my home and have it disabled in the home network. I needed to disable the IPv6 system in vRA. So, I did the following on vRA 8.6: sysctl -w net.ipv6.conf.all.disable_ipv6=1 then ran a reboot. While I was also in in the system, I added DNS records to the "hosts" file just to help the system. I hope this helps others like me who don't have IPv6 running in the homelab. Have a great day! Trey
