Hello :-)<br />
I am configuring dns scavenging in my dns / dhcp. currently the dhcp lease is 6 days, so according to the question <a href="https://www.experts-exchange.com/questions/29093013/DNS-Scavenging-Best-Practice.html" rel="ugc">https://www.experts-exchange.com/questions/29093013/DNS-Scavenging-Best-Practice.html</a>&nbsp;I've defined the no-refresh and refresh values for 3 days each (50% dhcp lease). So the DNS option &quot;allow automatic deletion of obsolete records&quot; should be set to same dhcp lease (6 days)?<br />

DNS Scavenging and DHCP lease

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

DHCP

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
