IP Addresses and DNS Host Name Retention
Articles and Tips: qna

Q.
I am using Netware 5.1 Dynamic DNS (Domain Name Services). After the DHCP server issues an IP address, it updates our DNS. However, I find that the DNS server seems to retain these forever. Computers that connected once six months ago still appear in the DNS tables.
I have looked but cannot find a setting to "flush" these old entries. How do I do that?

Dear Flushing: They have to be "flushed" manually. Something you may not have noticed, however, is that it's only the host name that stays in DNS. When an IP address is released, the address is removed from the DNS settings, leaving only the host name portion behind. If the same host is used again, the DNS will be updated with the new address that it gets.
