  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.
