dnsmasq option6

Dnsmasq is a lightweight DNS and DHCP server software that can be used to provide DNS and DHCP services to a small network. The "option6" in Dnsmasq refers to DHCPv6 options, which are used to provide additional configuration information to DHCPv6 clients.

DHCPv6 options are similar to DHCP options in IPv4, but they are used to provide IPv6-specific configuration information. Some common DHCPv6 options include:

- DNS Server: Specifies the IP address of the DNS server that the client should use.
- Domain Name: Specifies the DNS domain name that the client should use.
- NTP Server: Specifies the IP address of the NTP server that the client should use.
- SIP Server: Specifies the IP address of the SIP server that the client should use.

To configure DHCPv6 options in Dnsmasq, you can use the "dhcp-option" directive in the dnsmasq.conf file. For example, to specify the DNS server address, you can add the following line to your dnsmasq.conf file:

dhcp-option=option6:dns-server,2001:db8::1

This will instruct Dnsmasq to provide the DNS server address "2001:db8::1" to DHCPv6 clients. You can also specify multiple DHCPv6 options by adding multiple "dhcp-option" directives to your dnsmasq.conf file.
