How Do You Whitelist MTCaptcha Service For Firewalls

For environments where websites/services have to be explicitly whitelisted in the firewall, the ports are 80 (HTTP) and 443 (HTTPS) and the full list of MTCaptcha Plugin & API service IPs are:

  • 52.214.217.96
  • 35.165.137.56
  • 13.228.176.242
  • 13.234.26.164
  • 18.228.103.117
  • 18.162.183.0
  • 47.52.173.54

MTCaptcha Javascript Plugin uses a redundant dual-domain dual-network design which allows it to be delivered via both high performance dynamic CDN edge nodes as well as the more manageable and persistent static edge nodes IP’ed above.
