dnsmasq是一种轻型的DNS和DHCP服务器软件。它支持IPv4和IPv6协议,并且可以为网络中的设备分配IP地址和域名解析服务。dnsmasq还可以通过MAC地址过滤来限制网络访问。
要启用IPv4和IPv6支持,您需要在dnsmasq配置文件中添加以下行:
```
listen-address=::1,127.0.0.1
```
这将使dnsmasq监听IPv6和IPv4地址。
要使用MAC地址过滤,请在dnsmasq配置文件中添加以下行:
```
dhcp-host=<MAC地址>,<IP地址>
```
其中,<MAC地址>是设备的MAC地址,<IP地址>是要分配给该设备的IP地址。可以指定多个dhcp-host行来添加多个设备。
例如,假设您想将MAC地址为12:34:56:78:90:AB的设备分配到IP地址192.168.0.100,您可以添加以下行:
```
dhcp-host=12:34:56:78:90:AB,192.168.0.100
```
这将使dnsmasq为该设备分配静态IP地址192.168.0.100。

dnsmasq dhcp ipv6 ipv4
Dnsmasq is a lightweight DNS and DHCP server that can be used to provide both IPv4 and IPv6 addresses to clients on a network. It is commonly used in small networks, such as home networks, to provide local DNS resolution and DHCP services.
To configure Dnsmasq to provide both IPv4 and IPv6 addresses, you will need to edit the configuration file (/etc/dnsmasq.conf by default) and add the following lines:
```
dhcp-range=192.168.1.50,192.168.1.150,12h
dhcp-range=::100,::200,constructor:eth0,ra-names,slaac,12h
```
The first line specifies a range of IPv4 addresses to be assigned to clients, while the second line specifies a range of IPv6 addresses to be assigned to clients. The "constructor:eth0" option specifies that the IPv6 addresses should be assigned based on the interface (eth0) that the client is connected to, while the "ra-names" and "slaac" options specify that the addresses should be assigned using Router Advertisement (RA) messages and Stateless Address Autoconfiguration (SLAAC).
You may also need to enable IPv6 support in Dnsmasq by adding the following line to the configuration file:
```
listen-address=::1,127.0.0.1
```
This specifies that Dnsmasq should listen on the IPv6 loopback address (::1) as well as the IPv4 loopback address (127.0.0.1).
Once you have made these changes, you can start or restart the Dnsmasq service to apply the new configuration.
dnsmasq 2.82 ipv6 mac mtu
dnsmasq 2.82 支持 IPv6,可以通过 `--enable-ra` 参数启用路由广告功能。关于 MAC 地址,dnsmasq 可以通过 `dhcp-host` 选项为特定的 MAC 地址指定固定的 IP 地址。至于 MTU,dnsmasq 不直接控制 MTU 大小,但可以通过 `dhcp-option=option:mtu,1500` 参数向 DHCP 客户端提供 MTU 信息。
