How to Fix "Server IP Address Could Not Be Found"

The "Server IP Address Could Not Be Found" error arises from DNS resolution problems, which hinder the system from converting domain names into their related IP addresses. Several factors produce this error: DNS configuration errors, server uptime instability, or server hardware problems. The identification of primary causes stands as the key to solving issues successfully.

If facing such an error, move to this blog to find out different solutions to identify and repair the issue. 

Solution 1: Stable Internet Connectivity

Connectivity problems can stem from faulty or outdated DNS records on someone’s system. Here’s the procedure to refresh the DNS cache:

Windows

• Open Command Prompt with admin rights and execute: 

ipconfig /flushdns

macOS

• Open Terminal and execute:

sudo killall -HUP mDNSResponder

Solution 3: Analyze the Host File

To fine-tune domain name lookups, the host file can be utilized to alter DNS settings, providing control over the domain-to-IP mapping. You can check and perform modification in the host file via following procedure:

Modify the Hosts File

Copy link

• Use Notepad for hosts files edits on Windows systems but users must select between Nano or Vi text editors for macOS/Linux platforms.
• Each line of the file needs careful inspection to find any errors or incorrect access causing the issue.
• After editing, save the changes and close the editor.

Reload DNS Service

When issues persist, server configuration issues might be the culprit. To verify and correct server setup follow this procedure:

• Check all DNS records of your domain for proper configuration. Digital DNS tools and Network Services Lookup tools can be used to verify that DNS records function correctly.

• The server firewall requirements must include DNS traffic authorization. Modify firewall settings to enable DNS query transmission if needed.

• Performing a server restart of DNS services will rectify any configuration issues, resulting in improved connectivity. Run below command to restart the named service on a Linux server.

sudo systemctl restart named

Solution 5: Update Network Drivers
