Configuring IPv6 Addresses

The web console allows you to configure an IPv6 address or an IPv6 address range. The following are some configuration guidelines.

  • Worry-Free Business Security accepts standard IPv6 address presentations.

    For example:

    2001:0db7:85a3:0000:0000:8a2e:0370:7334

    2001:db7:85a3:0:0:8a2e:370:7334

    2001:db7:85a3::8a2e:370:7334

    ::ffff:192.0.2.128

  • Worry-Free Business Security also accepts link-local IPv6 addresses, such as:

    fe80::210:5aff:feaa:20a2

    Warning:

    Exercise caution when specifying a link-local IPv6 address because even though Worry-Free Business Security can accept the address, it might not work as expected under certain circumstances. For example, Security Agents cannot update from an update source if the source is on another network segment and is identified by its link-local IPv6 address.

  • When the IPv6 address is part of a URL, enclose the address in square brackets ([]).

  • For IPv6 address ranges, a prefix and prefix length are usually required. For configurations that require the server to query IP addresses, prefix length restrictions apply to prevent performance issues that may occur when the server queries a significant number of IP addresses. For example, for the Outside Server Management feature, the prefix length can only be between 112 (65,536 IP addresses) and 128 (2 IP addresses).

  • Some settings that involve IPv6 addresses or address ranges will be deployed to Security Agents but Security Agents will ignore them. For example, if you configured the smart protection source list and included a Smart Protection Server identified by its IPv6 address, pure IPv4 Security Agents will ignore the server and connect to the other smart protection sources.
