Overview of the Block Page IP Addresses used by OpenDNS
When a page is blocked by the OpenDNS service, our DNS resolvers display a block page instead of the page with the blocked content. These block pages are served from OpenDNS servers. The anycast IP address and associated block type for these servers are outlined in the table below.
Recent infrastructure updates have required changes to the IP addresses that are provided as a response to blocked requests. We do not expect these IPs to change again in the near future, but if they did change, that update would be included in this article.
