+## Error 1000: DNS points to prohibited IP
+
+This error indicates that a Cloudflare DNS record points to a prohibited IP, blocking access to the requested domain.
+
+### Common causes
+
+Cloudflare halted the request for one of the following reasons:
+
+- An A record within your Cloudflare DNS app points to a [Cloudflare IP address](https://www.cloudflare.com/ips/), or a Load Balancer Origin points to a proxied record.
+- Your Cloudflare DNS A or CNAME record references another reverse proxy (such as an nginx web server that uses the proxy_pass function) that then proxies the request to Cloudflare a second time.
+- The request `X-Forwarded-For` header is longer than 100 characters.
+- The request includes two `X-Forwarded-For` headers.
+- The request includes a `CF-Connecting-IP` header.
+- A Server Name Indication (SNI) issue or mismatch at the origin.
+
+### Resolution
+
+- If an A record within your Cloudflare DNS app points to a [Cloudflare IP address](https://www.cloudflare.com/ips/), update the IP address to your origin web server IP address. Reach out to your hosting provider if you need help obtaining the origin IP address.
+- There is a reverse-proxy at your origin that sends the request back through the Cloudflare proxy. Instead of using a reverse-proxy, contact your hosting provider or site administrator to configure an HTTP redirect at your origin.

+
+## Error 1001: DNS resolution error
+
+This error indicates a DNS resolution failure preventing access to the requested domain.
+
+### Common causes
+
+- A web request was sent to a Cloudflare IP address for a non-existent Cloudflare domain.
+- An external domain that is not on using Cloudflare has a CNAME record to a domain active on Cloudflare
+- The target of the DNS CNAME record does not resolve.
+- A CNAME record in your Cloudflare DNS app requires resolution via a DNS provider that is currently offline.
+- [Always Online](/cache/how-to/always-online/) is enabled for a [Custom Hostname (Cloudflare for SaaS)](/cloudflare-for-platforms/cloudflare-for-saas/) domain.
+
+### Resolution
+
+A non-Cloudflare domain cannot CNAME to a Cloudflare domain, unless the non-Cloudflare domain is added to a Cloudflare account.
+
+Attempting to directly access DNS records used for [Cloudflare CNAME setups](/dns/zone-setups/partial-setup) also causes error 1001. For example, `www.example.com.cdn.cloudflare.net`.
+
+Disable [Always Online](/cache/how-to/always-online/#enable-always-online), if using [Custom Hostname (Cloudflare for SaaS)](/cloudflare-for-platforms/cloudflare-for-saas/) domain.

+
+## Error 1002: DNS points to Prohibited IP
+
+This error indicates that a Cloudflare DNS record points to a prohibited IP, preventing proper domain resolution.
+
+### Common causes
+
+- A DNS record in your Cloudflare DNS app points to one of [Cloudflare's IP addresses](https://www.cloudflare.com/ips/).
+- An incorrect target is specified for a CNAME record in your Cloudflare DNS app.
+- Your domain is not on Cloudflare but has a CNAME that refers to a Cloudflare domain.
+
+### Resolution
+
+Update your Cloudflare A or CNAME record to point to your origin IP address instead of a Cloudflare IP address:
+
+1. Contact your hosting provider to confirm your origin IP address or CNAME record target.
+2. Log in to your Cloudflare account.
+3. Select the domain that generates error 1002.
+4. Select the **DNS** app.
+5. Click **Value** for the A record to update.
+6. Update the A record.
+
+To ensure your origin web server does not proxy its own requests through Cloudflare, configure your origin webserver to resolve your Cloudflare domain to:
+
+- The internal NAT'd IP address, or
+- The public IP address of the origin web server.
+
+## Error 1002: Restricted
+
+This error indicates that the domain resolves to a restricted or disallowed IP address.
+
+### Common cause
+
+The Cloudflare domain resolves to a local or disallowed IP address or an IP address not associated with the domain.
+
+### Resolution
+
+If you own the website:
+
+1. Confirm your origin web server IP addresses with your hosting provider,
+2. Log in to your Cloudflare account, and
+3. Update the A records in the Cloudflare DNS app to the IP address confirmed by your hosting provider.

+## Errors 1005 Access Denied: Autonomous System Number (ASN) banned
+
+This error indicates that access to the website is denied due to the banning of the Autonomous System Number (ASN).
+
+### Common causes
+
+The owner of the website (for example, `example.com`) has banned the autonomous system number (ASN) from accessing the website.
+
+### Resolution
+
+If you are not the website owner, provide the website owner with a screenshot of the 1005 error message you received.
+
+If you are the website owner:
+
+1. Retrieve a screenshot of the `1005` error from your customer
+2. Search the [**Security Events log**](/waf/analytics/security-events/) (available at **Security** > **Events**) for the **RayID**, or client IP Address from the visitor's 1005 error message.
+
+:::note
+Convert the UTC timestamp of the `1005` error to your local timezone when searching in the **Security Events log**.
+:::
+
+3. Assess the cause of the block and ensure the ASN is allowed under the [IP Access Rules](/waf/tools/ip-access-rules/) security feature.

+## Errors 1006, 1007, 1008 or 1106 Access Denied: Your IP address has been banned
+
+This error indicates that access is denied because your IP address has been banned.

+A Cloudflare customer blocked traffic from your client or browser.

+Error 1006 also occurs in the Cloudflare **Workers** app under the **Preview** tab when a customer uses **[Zone Lockdown](/waf/tools/zone-lockdown/)** or any other Cloudflare security feature to block the Google Cloud Platform IPs that the **Preview** tab relies upon.
+:::
+
+### Resolution
+
+Request the website owner to investigate their Cloudflare security settings or allow your client IP address. Since the website owner blocked your request, Cloudflare support cannot override a customer's security settings.
