Use this article to resolve conflicts when adding an IP address to a Site.

This error appears when the IP address is already assigned elsewhere in the DNSFilter system. The IP may be:

• Assigned to another Site within the same account
• Assigned to a different DNSFilter account

Each public IP address can only be associated with one account at a time.

Dynamic or shared IP addresses

Organizations using shared or dynamic public IP addresses (for example, satellite or residential internet providers, e.g., Starlink, Comcast, AT&T) may encounter conflicts more frequently.

If the external IP address changes regularly, configure a Dynamic DNS (DDNS) hostname instead of assigning the raw IP address. This prevents conflicts when the provider reassigns the IP.

Standard account

1. Navigate to Deployments and select Sites
2. Use the browser search function to locate the IP address across all Sites
3. Remove or update the duplicate IP address

If the IP address does not appear within the account and the error persists, contact Support and provide:

• The IP address
• The Site name where the error occurs

MSP account

For MSP dashboards, use the API to review all IP addresses associated with the account:

GET https://api.dnsfilter.com/v1/ip_addresses

Search the returned results for the conflicting IP address and update or remove it as needed.

If the IP address does not appear within the account and the error persists, contact Support and include:

• The IP address
• The affected Site and Organization name
