From a binary standpoint, IPv6 is NO different than IPv4. The only
separation is that the end result is in hex, not in decimal.
Bits 17-32
130 = 0000 0001 0011 0000
150 = 0000 0001 0101 0000
Mask= 1111 1111 1000 0000
|<-- 25 bits are set for the mask, hence a /25
Apply 0000 0001 0--- ---- the mask to get 0100 (0's designate the starting
point for your mask represented by the -'s)
No different than IPv4 subnetting.

Subject: IPV6 Route Summarization
Guys,
Can anyone help me understand ipv6 route summarization?
Example
2001:130:1:6:: /64
2001:150:1:6::6/128
2001:150:1:2::2/128
Answer is 2001:100::/25 but how I am confused ..
Regards,
Ubaid
