General Restrictions

  • UDP communication isn’t allowed.
  • Ports other than the standard 80 and 443 are blocked; http://example.com/ and https://example.com/ are acceptable targets, for example, but http://example.com:8080 would be rejected.
  • The Massive Network is intended to optimize delivery of content that could be reasonably considered “family friendly” to a (currently) worldwide userbase (in the future, regional distinctions are planned), so potentially dangerous or offensive content isn’t allowed.

A request that’s blocked due to any of these protocol, port, or content restrictions will fail with a 452 Disallowed Content error message.

Restricted Domains

  • We restrict access to content that is generally used to evade the law or site TOS policies. If you are getting blocked from accessing certain content that you have a legitimate reason to access, then contact support to complete our KYC process to gain access.

Port 25

  • Port 25 cannot be opened on our residential proxy network. If you want to use residential proxies to test email sending, you can request access for Port 587 or Port 465.

Request access

Contact support if you have questions about our policies or want to complete KYC to gain access to content that is restricted by default.
