doesn't cache any DNS information - it simply calls fping with

The name server won't/shouldn't cache anything longer than the
TTL on the zone A record. [Which should be in your control in
this case.]<br>

and works fine. [I'd guess you could update a DDNS entry by
setting up the PPPoE in your router - virtually all have
provision to update a ddns record when the interface changes.</span></blockquote>
I know. OpenWRT which I'm using of course can do it.<br>
<br>
I think I'll go that route.<br>

Thanks for your comments.<br>
