Still running 384.17 on AC86U for my network router. Having occasional reliability issues with the router failing to time sync after reboot, causing all kinds of havoc. Primary address is pool.ntp.org Just tried adding a hardcoded IP address as a secondary server to a NIST Stratum A destination which seemed to solve it for the moment. I'm considering the benefits of using a list of ip addresses as primary (I assume I can do that with comma delineation) to remove DNS resolution as a possible glitch but wonder if there is something else I'm doing wrong. Thoughts?
