# “IP address from domain is not valid” – Troubleshooting Guide

Walkthrough of handling IP Invalid error when trying to connect a domain.

## When connecting your domain, you might see the following error message:

> **“IP address from domain is not valid.”**
>

## The domain doesn’t have an active A record

Your domain doesn't currently resolve/point to a valid IP address.

In other words, if someone tries to visit your domain in a browser, nothing loads there's no website or server responding at that address.

Domains must have a valid IP before they can be added for monitoring.

## **How to Fix This Error**

If you see **“IP address from domain is not valid”** when connecting your domain, you can easily resolve it using one of our built-in solutions:

### **1\. Domain Masking**

Routes your secondary domains through **our private network of clean IPs**.  
This helps:

-   Protect your **main domain reputation** during cold outreach
    
-   Prevent **Google spam complaint notifications** (spoofing alerts)
    
-   Scale easily with **hundreds or thousands of masked domains**
    

### **2\. Hosted Redirects**

Simpler version of masking, also points your domain to our clean IPs, improving **deliverability** and ensuring your domain resolves properly.

### **Why These Solutions Work Better**

-   **Fixes the error** by assigning your domain a valid A record
    
-   **Improves domain reliability** by routing through our clean, high reputation IPs
    
-   **Shields your main domain** from blacklists or reputation issues
    

### **Next Steps**

1.  Choose **Domain Masking** or **Hosted Redirects** from your dashboard
    
2.  Copy the **A record** provided by EmailGuard
    
3.  Add it to your **DNS settings** under your registrar (Namecheap, GoDaddy, etc.)
    
4.  Once DNS updates, reconnect your domain
