IPv6 Support for FTP, FTPS, SFTP and HTTP/S

Serv-U supports FTP, FTPS, SFTP, web and mobile transfers (HTTP/S) using both IPv6 and IPv4. Future-proof your business and avoid IPv4 address exhaustion by deploying Serv-U today.



Total IPv6 Support

  • Supports long form IPv6 addresses (e.g., "1111:2222:3333:4444:5555:6666:7777:8888")
  • Supports short form IPv6 addresses (e.g., "1111::7777:8888")
  • Implements RFC 2428 ("FTP Extensions for IPv6 and NATs")
  • Supports wildcards (e.g., "*:*") and CIDR in access control rules
  • Supported on FTP, FTPS, SFTP, HTTP (web/mobile) and HTTPS listeners

Migrate Without Affecting IPv4 Operations

  • Separate listeners for IPv4 and IPv6 protocols
  • Optionally, use Serv-U Gateway to deploy IPv6 listeners on separate machine
  • IPv4 and IPv6 wildcards in access lists are treated separately (e.g., "*.*.*.*" vs. "*:*")

Requires No Special Knowledge

  • Domain creation wizard automatically adds IPv6 listeners
  • IPv6 listeners are listed with and behave like existing IPv4 listeners

Serv-U has natively supported IPv6 since Serv-U version was released on May 17, 2010. It has since been independently recognized as the most interoperable IPv6-ready FTP server in the market.
