Unable to write an IPV6 address.

It is impossible to manually write an address with a subnet mask in the ipv6 address, such as 2405:a590:5000:1200::15/64. If /64 is added, the address will disappear after saving. The software interface displays ：IPv6 0xIP 1xGW 1xDNS, (GW and DNS are valid because /64 is not written), but if I do not write /64, the valid address will become 2405:a590:5000:1200::15/ 0, which is obviously wrong.
I don't know if I wrote it wrong or if it's a software bug. .

Re: Unable to write an IPV6 address.

Back when we implemented the IPv6 feature, Windows automatically used /64 when no (or /0) was provided as the prefix length. So /64 wasn't saved with the preferences (in contrast to all other values). This seems to have changed and you are absolutely right that it's not OK right now. Thanks for reporting this issue.

We have reworked this today and it will be fixed in the next version.
Here is a preview of what it's going to look like:

/64 will be the default value, but of course can be edited manually.
It is also possible to enter something like 1::/128 as the IP and it will be automatically split into 1:: and 128 for both columns.
