IPv6 Subnet Calculation

IPv6 address formatting is sometimes very difficult. But website www.dnskey.net is making it easier. There are lots of web pages but this one is the simplest and very fast. If you want to divide your /32 subnet to /35s just write your prefix and submit!

Below is the output of /32 prefix divided into /35 subnets.

------------------------------------------------------
Prefix entered  => 2001:0DB8::/32 
Correct /32 prefix =>      2001:0DB8:0000:0000:/32
Subnet mask            =>      FFFF:FFFF:0000:0000:
You want /35 from =>      2001:0DB8:0000:0000:/32
Number of /35 subnets =>   8 
------------------------------------------------------
/35 prefixes 
------------------------------------------------------
2001:0DB8:0000:0000::/35  
2001:0DB8:2000:0000::/35  
2001:0DB8:4000:0000::/35  
2001:0DB8:6000:0000::/35  
2001:0DB8:8000:0000::/35  
2001:0DB8:A000:0000::/35  
2001:0DB8:C000:0000::/35  
2001:0DB8:E000:0000::/35
