16 IPv6 -> /124

abat

A few more than that: 18,446,744,073,709,551,616

or maybe you mean the number of group in a full IPV6 address...it is 8...

from wiki..

IPv6 addresses are represented as eight groups of four hexadecimal digits separated by colons,
 for example 2001:0db8:85a3:0042:1000:8a2e:0370:7334, 
but methods of abbreviation of this full notation exist.

Ah I get it now. I was just counting hexadecimal digits and not bits. Thanks
