The appreciable difference of Open DNS is not in performance over other DNS. The advantage of Open DNS over other DNS products is the added features of typo correction and fishing philter, and how unintrusively those features operate.
WINs[ windows internet naming service] tracks the relationships between host names and IP address, DNS [Nomain name service] is more popular because it works on all platforms.
DNS hijacking and DNS poisoning are both types of cyber attacks that target the Domain Name System (DNS) to redirect users to malicious websites. DNS hijacking involves an attacker gaining control over a DNS server or domain name, allowing them to redirect users to fake websites or intercept their traffic. This can lead to sensitive information being stolen or users being tricked into downloading malware. DNS poisoning, on the other hand, involves an attacker corrupting the DNS cache of a server or network, leading to legitimate domain names being redirected to malicious IP addresses. This can result in users unknowingly accessing fake websites or being exposed to phishing attacks. Both DNS hijacking and DNS poisoning can have serious implications for internet security, as they can compromise the integrity of the DNS system and lead to users unknowingly interacting with malicious content. This can result in data breaches, financial losses, and damage to an individual's or organization's reputation. It is important for users and organizations to implement strong security measures, such as using secure DNS servers and regularly monitoring for suspicious activity, to protect against these types of attacks.

You generally don't require a DNS configuration if you are not going to browse the internet..A DNS is essential only if you want to browse websites using their domain name.In this case, you are not using internet, hence may not require DNS configuration.Advanced info:-However, even if no DNS is specified, OS such as windows always has built in DNS resolution of the loopback IP 127.0.0.1 resolved to "localhost" by default and hence this may only be needed for intranet purposes

The main advantage to DNS is that Internet users only need to know the URL instead of the IP address to get to a website. The main disadvantage with DNS is that there may be problems finding the correct website when the IP address of that site changes.
There are many more than three protocols which can operate at the application layer. Some of these are; Telnet FTP TFTP SMTP IMAP POP DNS RARP BOOTP SNMP CMOT
DNS translates ip addresses into names which are easy read and remember for people.
One can increase the speed of internet browsing by changing their DNS server address. A list of DNS servers can be found on the Comcast website. Changing the DNS address to a more reliable one should increase the browsing speed of the computer.
The "DNS server failure" error in Firefox usually occurs when the web browser is unable to establish a connection to the DNS server to resolve domain names. Here are some possible solutions: Check your internet connection: Make sure your internet connection is working correctly by trying to access other websites. If you're not able to access any websites, then the problem is with your internet connection. Clear the DNS cache: Sometimes, the DNS cache can become corrupted, leading to this error. To clear the DNS cache, open the command prompt and type "ipconfig /flushdns". This will flush the DNS cache. Try a different DNS server: You can try using a different DNS server, such as Google DNS (8.8.8.8) or OpenDNS (208.67.222.222). To change your DNS server, go to your network settings and change the DNS server address. Disable DNS prefetching: DNS prefetching is a feature in Firefox that can sometimes cause the "DNS server failure" error. To disable DNS prefetching, open Firefox and go to "about:config". Search for "network.dns.disablePrefetch" and set it to "true". Restart your modem/router: Sometimes, restarting your modem or router can fix the problem. If none of the above solutions work, you may need to contact your internet service provider (ISP) or IT department for further assistance.
