History

Brad Fitzpatrick 8d6cf14456 net/dnscache: don't do bootstrap DNS lookup after most failed dials If we've already connected to a certain name's IP in the past, don't assume the problem was DNS related. That just puts unnecessarily load on our bootstrap DNS servers during regular restarts of Tailscale infrastructure components. Also, if we do do a bootstrap DNS lookup and it gives the same IP(s) that we already tried, don't try them again.
