IP Addresses

We are using the following IP address ranges:

  • SSL Labs - 64.41.200.0/24 (IPv4) & 2600:C02:1020:4202::/64 (IPv6)
  • SSL Pulse - 64.39.109.20
  • Development SSL Labs server - 104.130.202.77 (IPv4) & 2001:4801:7827:102:93a4:e8aa:5bca:d1f (IPv6)

 

Limitations

At present, SSL Labs has the following limitations:

  • SSL Labs currently uses Mozilla CA certificate store only. If the root is not there we report it as not trusted. A future SSL Labs version will report trust for each major root store separately.
  • Certificate trust is not checked in handshake simulation, we only perform TLS handshake.
