Yes, see the added documentation:

+@item ip6-net=@var{addr}[/@var{int}]
+Set IPv6 network address the guest will see. Optionally specify the prefix
+size, as number of valid top-most bits. Default is fec0::/64.
+                         
+@item ip6-host=@var{addr}
+Specify the guest-visible IPv6 address of the host. Default is the 2nd IPv6 in
+the guest network, i.e. xxxx::2.

+@item ip6-dns=@var{addr}
+Specify the guest-visible address of the IPv6 virtual nameserver. The address
+must be different from the host address. Default is the 3rd IP in the guest
+network, i.e. xxxx::3.

Most probably you'll want to set ip6-net to something else than
fec0::/64 since OSes usually prefer IPv4 over fec0::/64.
