IP Address range and Port Information

Customers using a proxy server or strict firewall may need to whitelist Hightail's services to gain access. 

Hightail encourages customers to use domain-based white listing if possible.  Hightail uses SSL/TLS (tcp port 443) for all connections under the following domain names:

  • hightail.com
  • spaces.hightail.com
  • download.spaces.hightail.com
  • upload.spaces.hightail.com

The Spaces website also uses references following 3rd party websites:

  • nr-data.net

If IP addresses are required for whitelisting, customers should pull address ranges directly from Amazon Web Services and Fastly

Hightail sends SMTP e-mail notifications from the following domains:

  • hightail.com
  • hightailmail.com
  • spaces.hightailmail.com

e-mail notifications are relayed through the following IP address:  o1.spaces.hightailmail.com
