Connection-Specific DNS Suffix = Wrong
I have a Windows 11 workstation with static IPv4 and DHCP IPv6. The machine is receiving the wrong Connection-Specific DNS Suffix ".bo.".
Testing.. Disabling IPv6 and refreshing provides a blank connection suffix. Enable IPv6 and it returns ".bo.".
Its unclear if this is a random name or clipped from the actual domain name. "in.bounce.notreal".
The DNSmasq.conf contains the correct domain name and does not contain ".bo." at all. I am using RA from dnsmasq, system RA is not enabled.
domain=in.bounce.notreal
dhcp-range=tag:igc1,10.10.1.234,10.10.1.254,86400
dhcp-range=tag:igc1,::100,::1ff,constructor:igc1,slaac,ra-names,64,86400
ra-param=igc1,60,1200
Update:
After additional testing the domain name is mangled from DNSmasq "DHCP FQDN" ✅ and "DHCP default domain", if a replace "in.bounce.notreal" with "testme.internal" the Connection-specific DNS suffix is "te.int" instead of ".bo.".
