Your company is designing its network. The network will use an IPv6 prefix of 2001:DB8:BBCC:0000::/53 . You need to identify an IPv6 addressing scheme that will support 2000 subnets.
Which network mask should you use?
A.
/61
B.
/62
C.
/63
D.
/64

I don`t quite get this ipv6 stuff.. could anyone explain please? I thought you would need 11 “free” bits to be able to define a maximum of 2048 subnets(2^11), and thus the netmask should be 64-11=53 wich is obviously not an option here – what am I missing?
oops, I see I got this one backwards and upside down. The mask for each subnet needs to be /64 in order to fit 2000 subnets within the 11 “free” bits. Then answer D is then correct of course. My bad.
