<-- Hi Danny: a ping from the Pi still returns the old (209.x.x.x) address; I rebooted the Pi to ensure any cached DNS entries get flushed. I've just logged into my D-STAR system on the same network (so NAT'd behind the same router) and get the same issue. So perhaps the DNS changes have not propagated through. I'll wait a little longer and, if needed, I'll hard-code the change in my host file to force the new IP... until the DNS changes catch-up.Ramesh,
Until your pi can resolve the address correctly (for whatever reason) it's still a problem.
Does "ping stats.allstarlink.org" return the new address or the old?
Does it resolve correctly from another PC on your LAN? etc.
