What is the maximum range that it can provide? What would be the starting and ending addresses if this full range were utilized? 4) Explain how a DHCP lease works. When a device tries to connect to the internet the network requests an IP address. The DHCP server leases the device an IP address that is then forwarded to the network via the router. The DHCP updates the appropriate servers with the address and other information. The device then accepts the address and the DHCP reallocates the address or leases one that’s available. Then the device is no longer connected and the address becomes available again. 5) Describe the purpose of the forward and reverse DNS lookup zones? How do they differ? DNS is used to translate domain names to IP addresses. A forward lookup zone is a DNS in which the hostname to IP relationship is stored; when a computer requests the IP address of a certain hostname this zone is queried and it returns the result. A reverse lookup zone does the opposite; when the computer requests the hostname of an address this zone is queried and the result is returned.
