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:
| 198.37.148.95 | o1.spaces.hightailmail.com |
