FAQ – IP Address Issues 🛠️

What to do if you’re having trouble with your IP address

If you’re experiencing IP address issues—such as being blocked, unable to access services, or errors in control panels—here are the steps our support team at IP ServerOne recommends:

🔒 1. Check if your IP is blocked by our firewall

• Service tools like WHM or SSH may be inaccessible if your IP is blocked.
• Identify your current public IP (visit a site like WhatIsMyIPAddress.com).
• Contact our support team with your IP to verify if it is blocked, and we’ll assist in unblocking it.

🧪 2. Run a ping test to check connectivity

• On Windows: open Command Prompt and run ping <your-server-domain-or-IP.
• A reply confirms network reachability.
• A “Request timed out” or no reply could indicate firewall or network issues.

🛠️ 3. Identify firewall blocks on managed control panels

If you’re blocked from DirectAdmin, cPanel, or WHM:

• • Log in via SSH (as root).
  • Check firewall rules using:

iptables -nvL | grep <your-IP> 
csf -g <your-IP>

• These commands show if your IP is actively blocked.

✉️ 4. Diagnose email-related blockages

• You may have trouble sending email if your IP is blacklisted.
• Check your public IP’s status using blacklist lookup tools (e.g., MXToolbox).
• If blacklisted, follow the tool’s guidance to remove the listing after correcting the issue.

🔄 5. Look into session-related errors in cPanel/WHM

• “IP address has changed!” errors occur with dynamic IPs or multiple device logins.
• Try logging out and back into cPanel.
• If problems persist, and you have WHM admin access, adjust Cookie IP Validation in WHM’s Tweak Settings.

✅ 6. Double-check basics

• Ensure you’re using correct credentials for WHM, SSH, DirectAdmin, etc.
• Verify your local network allows outgoing traffic to required ports (e.g., 22, 2087).
• Confirm the server is online—via your client portal or through ping tests.

📞 7. Still stuck? Reach out to Support

Provide the following when you open a ticket or call us:
