Unable to Resolve Target System Name in Tracert

The error "Unable to resolve target system name" in the tracert (or traceroute on Linux/Mac) command occurs when the system cannot resolve the hostname or domain name provided to its corresponding IP address.

For closely related tracert / DNS topics, see Tracert — Unable to Resolve (original), Fix "EAI_NONAME" — Complete DNS Resolution Guide, and SSH ssh_init — Flush DNS Cache.

• Ensure the domain or hostname is typed correctly.
• Example:

tracert example.com

• Incorrect usage:

tracert http://example.com

• Fix: Remove http:// or https://.

• Use the ping command to check if the system can resolve the hostname:

ping example.com

• If this also fails, there is likely a DNS issue.

• If the hostname cannot be resolved, use the server IP address directly:

tracert 192.168.1.1

• Ensure the system has an active internet connection.
• Test by accessing a known website like google.com.

Clear your system DNS cache to resolve possible conflicts.

On Windows:

1. Open Command Prompt as Administrator.
2. Run:

ipconfig /flushdns

If the issue persists, try using a public DNS server like Google DNS or Cloudflare DNS.

• Google DNS:
• Primary: 8.8.8.8
• Secondary: 8.8.4.4
• Cloudflare DNS:
• Primary: 1.1.1.1
• Secondary: 1.0.0.1

Steps to Change DNS (Windows):

1. Go to Control Panel > Network and Sharing Center > Change adapter settings.
2. Right-click on your active network and select Properties.
3. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
4. Enter the public DNS server addresses.

• Ensure your firewall or antivirus software is not blocking tracert.
• Temporarily disable the firewall to test if it resolves the issue.

• Use a tool like WHOIS Lookup to check if the domain is still active.
