When trying to add an IPv4-mapped IPv6 address, for example "0:0:0:0:0:ffff:ac1f:c179/128", the GUI throws this error: "Error parsing IP address: 0:0:0:0:0:ffff:ac1f:c179/128"

Impact

The GUI throws an error and it's not possible to add the IPv4-mapped IPv6 address.

Conditions

On the GUI Virtual Server configuration page, add an IPv4-mapped IPv6 address with any of these possible syntaxes: 0:0:0:0:0:ffff:ac1f:c179/128 ::ffff:192.168.0.128/128 ::ffff:ac1f:c179/128

Workaround

Add the IPv4-mapped IPv6 source address via tmsh: # create ltm virtual test_ipv6_00637978 destination ::0.433 source ::ffff:ac1f:c179/128
