If the IPv6 address is not reachable, ntpd does not seem to give up and try the IPv4 address. It looks to me like it just gives up. I did not notice any problem while I was on an IPv6 connected network at work or while on travel at a networking conference as they have IPv6 connectivity, but when I tried from home, where my broadband provider does not provide any IPv6 routing, ntp simply spits out messages that it failed to connect to each server. Is this a problem with the vendor code or is it the result of some FreeBSD patch? -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
