Following are some ways to resolve DNS issues:

• Check your cords and connections: If you're using wired connections, double-check that everything is correctly plugged in. If you're using a wireless NETWORK, ensure sure it's turned on and connected. Check to SEE if your router is turned on and working.
• Rule out ISP problems: Make sure you're not having problems with your Internet service provider by attempting to link with another device. If you can directly connect to your ISP without going through the router, do so.
• Reboot your router: Turn it back on after a minute and wait till the indicator lights cease blinking before attempting to connect.
• Scan for malware: In some situations, a VIRUS could be preventing you from accessing the internet. In this instance, you may have more pressing concerns to address before addressing IP connectivity.
• Examine your TCP/IP settings: These options control how your computer interacts with others. You could have recently updated these settings and attempted to manually enter them. Find "Manage network connections" in your computer's networking or control panel. Locate and tap on both IPv6 and IPv4 "Properties" under "Local Area Connections," "Properties." Make sure "Obtain an IP address automatically" and "Obtain DNS servers address automatically" are both checked.
• Clean out your DNS cache: Your computer's DNS cache is where it saves networking information from previous visits and efforts to connect to online SITES. The cache can get corrupted as a result of incorrect data. Type ipconfig /flushdns into the command prompt to flush, or clear, this cache. The DNS cache will now have to update the DNS information the next time you visit a website.
• Obtain a new domain name: Is your website address functional but taking you to an unfamiliar site? It's most possible that you neglected to renew the domain name.
  If necessary, update and reinstall the network adapter driver: When was the last time you updated your drivers? This may be causing problems, especially if you've upgraded your PC's hardware since purchasing it. You can fix DNS problems by manually searching for network device driver updates and updating them.
• Switch to Google's public DNS servers: Google's servers are usually more dependable and may be utilised without going via your ISP. You can change your DNS servers to Google's by altering the following properties in your Internet Protocol Version 4 (TCP/IPv4).
