I can confirm that your patch is working for my examples used before. 

Now, a range definition and "prefixlen 56" is recognized properly:

ifconfig:
|       inet6 dead:beef:1111:2222::2 prefixlen 56 
|       inet6 dead:beef:1111:2222::3 prefixlen 56 
|       inet6 dead:beef:1111:2222::4 prefixlen 56 
|       inet6 dead:beef:1111:2222::5 prefixlen 56 
|       inet6 dead:beef:1111:2222::6 prefixlen 56 

Thanks and with kind regards,
Michael
