openwrt dnsmasq

OpenWrt is a Linux-based operating system designed for embedded devices. It is a popular choice for routers and other networking equipment. One of the key components of OpenWrt is dnsmasq, a lightweight DNS and DHCP server.

Dnsmasq is used to provide DNS and DHCP services to devices on a network. It can act as a DNS server, resolving domain names to IP addresses, and as a DHCP server, assigning IP addresses to devices on the network. Dnsmasq is lightweight and easy to configure, making it a popular choice for small networks and home routers.

To configure dnsmasq on OpenWrt, you can use the LuCI web interface or the command line. The configuration file for dnsmasq is located at /etc/dnsmasq.conf. You can use this file to configure various aspects of the DNS and DHCP services provided by dnsmasq.

Some of the common configuration options for dnsmasq include:

- DHCP range: This specifies the range of IP addresses that can be assigned to devices on the network.
- Domain name: This sets the domain name that will be used for the network.
- DNS servers: This specifies the DNS servers that dnsmasq should use to resolve domain names.
- Hostname: This sets the hostname for the router or other device running OpenWrt.

Overall, dnsmasq is a powerful and flexible tool for providing DNS and DHCP services on a network. With OpenWrt, it is easy to configure and customize to meet the needs of your particular network.
