How to set DNS in dnsmasq?

The dnsmasq server can be configured via the /etc/dnsmasq. conf file (which contains well commented and explained options), and user-defined configuration files can also be added in the /etc/dnsmasq. d directory. DNS is enabled by default, so before making any changes, make sure to create a backup of /etc/dnsmasq.

How to disable DNS in dnsmasq?

On Linux Mint, dnsmasq is installed to cache DNS queries, and thereby speed up your Internet experience. The first part of disabling it is to change the configuration in /etc/NetworkManager/NetworkManager. conf by commenting out dns=dnsmasq . Next, you have to restart both the network-manager and networking services.

How to speed up dnsmasq?

If required, you can also increase the dnsmasq cache size. In that case, you need to find the line #cache-size=150. Remove the # and change 150 to any higher value until 10000 as per the available server resource. By increasing this value, your dnsmasq would be able to cache more names.

How to disable DHCP in dnsmasq?

By default, the DHCP is disabled in dnsmasq (check one example dnsmasq. conf file). To disable DHCP service in dnsmasq, in `/etc/dnsmasq. conf`, remove or disable the lines starting with “dhcp” and then restart the dnsmasq service.

Does dnsmasq have DHCP?

dnsmasq is a lightweight and simple program which enables issuing DHCP addresses on your network and registering the hostname & IP address in DNS. This configuration also allows external resolution, so your whole network will be able to speak to itself and find external sites too.

Should DHCP server be on domain controller?

Domain controllers do not require the DHCP Server service to operate and for higher security and server hardening, it is recommended not to install the DHCP Server role on domain controllers, but to install the DHCP Server role on member servers instead.

Can I use 0.0 0.0 DNS?

0.0 is not a valid destination address, this is simply an invalid configuration. DNS servers, like other regular IP services, need to be addressed by a valid destination IP address, ie. anything but 0.0. 0.0 and 255.255.

It tells a server to "listen" for and accept connections from any IP address. On PCs and client devices. A 0.0. 0.0 address indicates the client isn't connected to a TCP/IP network, and a device may give itself a 0.0. 0.0 address when it is offline.

What DNS server is dnsmasq using?

Please note that 127.0. 1.1 (and possibly others) indicates dnsmasq, and 127.0. 0.53 indicates systemd-resolved. If the current active connection is not managed by NetworkManager (and systemd-resolved), then the DNS servers will be enumerated in the file /etc/resolv.

Should I use dynamic DNS with VPN?

Dynamic allocation of WAN IP addresses necessitates using the Dynamic DNS (DDNS) facility so that VPN Clients can connect to the VPN server by looking up a Fully Qualified Domain Name address, rather than nominating the traditional fixed IP address.

Does 8.8 8.8 need DNS to work?

If your DNS is only pointing to 8.8. 8.8, it will reach out externally for DNS resolution. This means it will give you internet access, but it will not resolve local DNS. It may also prevent your machines from talking to Active Directory.

Should I use 1.1 1.1 DNS?

What is the difference between dnsmasq and DHCP?

The DHCP server integrates with the DNS server and allows local machines with DHCP-allocated addresses to appear in the DNS. dnsmasq caches DNS records, reducing the load on upstream nameservers and improving performance, and can be configured to automatically pick up the addresses of its upstream servers.
