Firewall IP Whitelist

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
  • 8.210.253.57
  • 8.217.100.38

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 at the IPs listed above.
