Name : dnsmasq Product : Fedora 37 Version : 2.89 Release : 2.fc37 URL : http://www.thekelleys.org.uk/dnsmasq/ Summary : A lightweight DHCP/caching DNS server Description : Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server. It is designed to provide DNS and, optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP for network booting of disk-less machines.
