Joined: Nov 19, Messages: What would happen if the DNS went down hackers, war, natural disaster, etc? If I had the ip address of a website, could I still access it?
Would websites still work, it would just be very difficult to access webpages or would they stop working? If typing the ip address of a website would allow me to access it, if I had the ip address of a site like YouTube, would the video suggestions on YouTube still work?
Also, my school is online, how likely is it that it would still work? The final test is to try a different browser. If using Firefox, try using Chrome or Safari to access the web.
If using a different browser fixes the problem, you may need to update the default browser. If updates do not work, consider uninstalling and reinstalling the software to see if it fixes the problem. Computers When a computer or router is first used, DNS settings are entered into the device to ensure they can connect to the appropriate DNS server.
Check DNS Settings. Then, check the DNS settings on the computer to confirm they are correct. Deactivate Firewall or Antivirus Programs. Firewalls and antivirus software can block IP addresses or websites. The easiest way to check is to deactivate the programs and try to connect to the internet. If successful, recheck the DNS configurations in the firewall and antivirus programs.
Disable Secondary Connections. If the computer has other open connections such as Bluetooth, disable all other connections to avoid conflicts.
On a Windows system, disable the peer-to-peer feature. Update Network Adapter Drivers. Check that network adapters are up-to-date. If not, update drivers and try connecting again. Routers Routers can cause problems connecting to DNS servers. Connect to the Ethernet. To determine if a router is the problem, switch to a cabled connection. Connect a computer to the router using an ethernet cable.
If using the ethernet connection solves the problem, the router is probably at fault. Confirm that the router is configured correctly. Restart the Router. Every website has its own web IP address. However, they are difficult to remember. So, most people use the domain name instead. DNS servers point users to the right location so that websites will load correctly. DNS errors happen when you are not able to connect to an IP address.
This type of outage usually occurs because you have lost the Internet or network connection. Occasional DNS outages are inevitable. However, not all of them are significant attacks and can be solved relatively easily. Not all connectivity issues are DNS issues. But it is not a DNS problem. Routers have their own CPU, memory, motherboard, and even an operating system. All of these components manage data traffic. An application performs a front-end transaction with a proxy, and the proxy does a whole load of back-end transactions with various content servers to construct the complete answer that it returns to the application.
Content servers don't query other content servers, and the only time that a proxy server talks to another proxy server is when it is forwarding the entire transaction for the forwardee to perform the grunt work.
One can configure multiple proxy servers for the client library code in applications programs to send their front-end queries to. In Microsoft terminology for Windows NT, these are the set of "preferred" and the set of "alternate" proxy DNS servers that one configures a workstation with.
These servers do not form any sort of a hierarchy. Clients pick amongst them arbitrarily, in ways that vary from client library to client library and according to various client library bugs , and they should all thus behave identically to one another for proper operation. Usually, ISPs provide at least a pair of identically behaving proxy DNS servers for customer use, so that if one server goes down the client libraries can fall back to the other.
