What is Google DNS?

Google Public DNS (IPv4: 8.8.8.8 and 8.8.4.4, IPv6: 2001:4860:4860::8888 and 2001:4860:4860::8844) is a free, globally distributed DNS service provided by Google. It helps resolve domain names faster and more securely.

Advantages of Using Google DNS

1. Faster Browsing Speeds:

• Google has a vast, distributed network of DNS servers optimized for speed.

• Reduced latency compared to some ISP DNS servers.

2. Enhanced Security:

• Google DNS protects against DNS spoofing and cache poisoning attacks.

• Supports DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) for encrypted queries.

3. High Reliability:

• Google's infrastructure ensures consistent uptime and reliability.

• Redundant servers reduce downtime risk.

4. Unfiltered Internet Access:

• Some ISPs filter or block certain websites; Google DNS avoids this issue.

• No redirections to ISP-sponsored pages.

Disadvantages of Using Google DNS

1. Privacy Concerns:

• Google collects DNS query logs, though it claims not to store personally identifiable data.

• Users concerned about privacy may prefer alternatives like Cloudflare (1.1.1.1).

2. May Not Work With Some ISPs:

• Certain ISPs enforce their DNS settings, preventing users from switching.

• Some services that rely on ISP-specific DNS configurations may not function properly.
