Thanks, Joseph. I tested clean installations of Ubuntu 1404, 1604, and 1610 and used the commands "dig @2001:4860:4860::8888 google.com a" and "dig @2001:4860:4860::8888 google.com a +tcp" to test. All systems are virtual machines running on the Windows Server 2016 Hyper-V hypervisor. I tested each operating system both as installed and with all current patches applied. Results are as follows:
Ubuntu 1404, kernel 4.2.0-27-generic, DNS UDP ok, DNS TCP ok. Ubuntu 1404, kernel 4.2.0-42-generic, DNS UDP ok, DNS TCP ok. Ubuntu 1604, kernel 4.4.0-31-generic, DNS UDP fail, DNS TCP ok. Ubuntu 1604, kernel 4.4.0-45-generic, DNS UDP fail, DNS TCP ok. Ubuntu 1610, kernel 4.8.0-22-generic, DNS UDP fail, DNS TCP ok. Ubuntu 1610, kernel 4.8.0-26-generic, DNS UDP fail, DNS TCP ok. I will test kernel 4.9-rc4 as you requested and report the results. Thanks.
