Dynamic update & DHCP W2K

[Mark.Andrews at nominum.com]

	File a bug report with MS.  The DHCP server should be cleaning
	up after itself.

	Also if you are running 8.2 rather than 8.2.3 you should look
	at http://www.isc.org/products/BIND/bind-security.html

> Hi,
> we are using W2K DHCP with dynamic update and ISC bind 8.2 on UNIX. When
> DHCP updates PTR records, we have the following situation into the
> .in-addr.arpa zone files, when, for example, the address 132 is reassigned
> by DHCP:
> 
> 132    900    IN    PTR    oldest.domain
>           900    IN    PTR    older.domain
>           900    IN    PTR    newname.domain
> 
> Where IP 132 is in fact assigned to newname.domain and nslookup reverse
> query answer with oldest.domain.
> Is it possible to purge stale PTR records ?
> 
> Thanks
