What is a Public DNS?

Public DNS (Domain Name System) refers to freely accessible DNS services provided by third-party organizations, distinct from the default DNS servers offered by Internet Service Providers (ISPs). While ISPs provide DNS servers by default, there are some reasons to consider switching to Public DNS servers, which offer various advantages

• Faster Performance: Public DNS servers, such as those offered by Google (8.8.8.8), Cloudflare (1.1.1.1), or OpenDNS, are often optimized for speed. This can result in quicker domain name resolution and faster loading times when accessing websites.
• Enhanced Security: Public DNS services often implement advanced security features, including built-in protections against phishing attacks and malware. This extra layer of security can help safeguard users from potential online threats.
• Improved Privacy: Using a public DNS can enhance user privacy by preventing ISPs from logging and potentially monetizing users' browsing data. Public DNS providers may offer more transparent data handling policies, contributing to a more private online experience.
• Bypassing Restrictions: In some cases, public DNS servers may help users bypass geographical restrictions imposed by ISPs, allowing access to content that might be otherwise restricted.

Making the switch to a public DNS server is typically straightforward. Overall, choosing a public DNS provider can contribute to a faster, more secure, and private internet experience.

What is a Wi-Fi Channel?

In the context of Wi-Fi, a channel refers to a specific frequency band used for transmitting data between a user device and the Wi-Fi connection. In the 2.4GHz band, commonly used by Wi-Fi routers, there are 12 available channels for data transactions. It's important to note that many Wi-Fi routers come with the default setting of automatically changing channels. When multiple networks operate on the same Wi-Fi channel, interference may occur, especially if neighboring networks have higher signal strength. This interference can lead to reduced network performance and slower internet speeds for users. To optimize Wi-Fi performance, it's advisable to:

• Manually select a less congested Wi-Fi channel to minimize interference.
• Regularly check and adjust Wi-Fi channels, especially in environments with numerous Wi-Fi networks.
• Consider using the 5GHz band, which provides more channels and reduced interference compared to the 2.4GHz band.

By managing Wi-Fi channels effectively, users can enhance the reliability and speed of their wireless connections.
