Leaves 76 /64 prefixes and 229 /48 prefixes.

There are 2^64 or 18,446,744,073,709,551,616 addresses in a /64 subnet.
There are 65536 /64 subnets in a /48 subnet.

Do the math: 76x18,446,744,073,709,551,616 plus 65536x229x18,446,744,073,709,551,616 total dynamic.wline.6rd.res.cust.swisscom.ch addresses
making the sum total (65536x229+76)x18,446,744,073,709,551,616 equals 15,007,820 /64 subnets, each with 18,446,744,073,709,551,616 addresses.
