help-why is cmd “netsh interface ipv6 show prefixpolicies” showing only one ipv4 prefix instead of several ipv4 & ipv6 prefixes?

[dwedwedwe]

A couple days ago, when I used the "netsh interface ipv6 show prefixpolicies" command on my Windows 10 system, it resulted in this standard result:

Precedence  Label  Prefix
----------  -----  --------------------------------
        50      0  ::1/128
        40      1  ::/0
        30      2  2002::/16
        20      3  ::/96
        10      4  ::ffff:0:0/96
         5      5  2001::/32

I do not know what changes I made (if any), but now when I run the same command, I get only this:

Precedence  Label  Prefix
----------  -----  --------------------------------
        10      4  ::ffff:0:0/96

Why is it showing only one ipv4 prefix, how to solve this anomaly?  Could this have any malicious implications?

Thanks for any advice

use (in administrator cmd probably)

netsh interface ipv6 reset

and restart
