Without DNS you would be typing

http://74.125.77.104 instead of www.Google.com

What are the differences between DNS hijacking and DNS poisoning, and how do they impact internet security?

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.

Network Error dns server failure in Firefox?

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.
