ntpd restart on IP address change the Debian way

[Bob <spam@homeurl.co.uk>]

Is there such a thing?

When my firewall / dhcp server / ntp server gets a fresh IP address from 
my ISP the ntp daemon stops responding to requests.

This is a well know bug [0] and there are a lot of posts about it but no 
consensus on a work around.

Any help?

Thanks

[0] it's so old a well known it's about to get rebranded as a 'feature'.
