Question: Why Run Your Own DNS?

Another reason for running your own recursive DNS server internally is network wide ad blocking.

Instead of installing a host based ad blocker on every device, just block those domains/hosts on your name server and everything that uses it is covered.

Can I make my own DNS server?

What are the advantages of a DNS server?

User Benefits

DNS servers allow standard Internet users to use Internet resources without having to remember port numbers and IP addresses. Even similar services, such as different areas of the website, may be hosted at different IP addresses for security reasons.

Why don’t we maintain our own DNS?

Why do we need a Domain Name System? Domain Name System allows users to have the same url or consistent domain name while IP addresses change frequently. We need DNS because without it users would need to keep on checking the IP addresses of others and of themselves to send messages or view sites.

What should I set my DNS server to?

To change your DNS server, head to Settings > Wi-Fi, long-press the network you’re connected to, and tap “Modify Network”. To change DNS settings, tap the “IP settings” box and change it to “Static” instead of the default DHCP. Depending on your device, you may need to check an “Advanced” box to see this setting.
