Move from or Compare IPv4 to IPv6 Address


IPv4

  • 32 bit long(4bytes)
  • Address= Network+Host
  • Network and Host portion depends on classes
  • Classes for identification depends upon the initial bits
  • Total no of IPv4 addresses are 4,294,967
  • Represented by dotted decimal or binary (192.168.100.1)


IPv6

  • 128 bit long(16bytes)
  • Basic architecture = (64 bits) network + (64 bits) host .
  • Host Portion often be the MAC address or interface identifier
  • Classes for identification depends upon the initial bits
  • Total no of IPv6 addresses are 340,282,366,920,938,463,463,374,607,431,770,000,000
