If you really want this range 2001:558:ff10:870:8000:0000:0000:0000 - 2001:558:ff10:870:8FFF:FFFF:FFFF:FFFF please change your prefix length to /68 .

No, the "range" 2001:558:ff10:870:8000::/65 encompasses the addresses:

2001:558:ff10:870:8000:0000:0000:0000 - 2001:558:ff10:870:8FFF:FFFF:FFFF:FFFF

Which does _not_ include 2001:558:ff10:870:f914:a7c1:42d1:faa1

This address:

Certainly lies within this range:
