How to fix All the Possible IP Address Errors

 

An IP address is a unique address that identifies a device on the Internet or a local network.

 

IP: Internet Protocol. Internet Protocol address is a numerical label assigned to a device that is connected to a computer network. 

 

Q. What does an IP Address do?

There are two primary functions of an IP address. 

 

First, the purpose of an IP address is to send and receive information. Second, an IP address allows the information or data to be sent and received between the two parties. Another function of an IP address is location addressing. 

 

But, networks are networks. Despite putting our best efforts, there still occur some faults, some errors that we can’t control. But we can fix them for sure. Some sites can help you regarding issues like access 192.168.86.1 IP address, which is a common problem among users.

 

 So, let us look at some of the possible errors that regularly occur and how to prevent them. 

 

Duplicate IP Address 

 

Cause: When two devices share the same IP. 

 

Error Message: “There is an IP address conflict.”

 

Cure: If you have installed a new device/server to your network, it may have its own DHCP server. Simply disable the DHCP server on the new device, and you are good to go.  

 

Prevention: By modifying the router’s configuration to begin assigning DHCP addresses near the top end of your subnet. This will leave the lower addresses spare for devices that require static IPs. 

 

DNS Error

DNS stands for The Domain Name System. 

 

Error Message: “IP Address could not be found,” “DNS name does not exist.”

 

Cure: Specific network devices can be assigned their own DNS servers. While checking the “IP Version (TCP/IP)” in settings, just select the option of ‘Obtain DNS server address automatically. 

 

Prevention: Your local router might be configured to operate as a DNS server, creating a DNS pass-through to your ISP’s servers. Changing your network’s DHCP settings to access your DNS servers directly can help. 

 

Local Network unable to Connect to the Internet

Cause: This is caused by intermittent failures which are hard to trace.  

 

Error Message: “Windows was unable to connect to this Network.”

 

Cure: The router can be rebooted. Troubleshoot the problems. You can also ask your network provider for help. 

 

Prevention: The only preventive measure for this make sure that you get a network from a reputed Internet provider. If the network still gives issues, it shall be solved with a single phone call.  

 

IP Address Exhaustion

Cause: You probably have run out of ‘allowed IP Addresses’ from your ISP. There is also a chance that the default address pool might be too small. 

 

Cure: The solution to this is to buy a Standalone Router or Wi-Fi access point with an integrated router. Also, you can adjust the size of the address pool to meet your network needs.  

 

Prevention: You shall make sure that any internet-connected network has a local router in operation with NAT or DHCP. The router should only be the device that is connected to the modem.

 

Single Workstation Unable to connect to the Network

Cause: This error implies that the entire network is healthy and the fault is in the hardware or the Software of the particular system. 

 

Error Message: “No Internet”

 

Cure: Abolish the bad cables, poor Wi-Fi network, and incorrect drivers. Also, check any firewall software on the device to ensure that required ports are open to the external Network (ports like 80, 443, 25, 587,110, and 995). 

 

Prevention: You might want to leave all workstation TCP/IP settings to ‘Automatically assigned.’ Use a DHCP server to hand out a uniform configuration to all the devices.

 

Unable to Connect to Local File

Cause: This occurs due to conflicts between mixed Security environments. Sometimes the different versions of the same operating system use slightly different security models. 

 

Error Message: “Default Printer could not be found.”

 

Cure: (a) Ensure the required services are running: The server, workstation, TCP/IP helper, and computer browser.

         (b) Check your Firewalls.

         (c) Ensure that all the workstations are on the Subnet.

         (d) Above all, you should check the permissions. 

 

Prevention: Follow all the steps with accuracy.
