Versions of IP Address
Internet Protocol Version 4 (IPv4)
– The most widely used version of IP address.
– IPv4 uses a 32-bit address scheme allowing for a
total of 232 addresses.
-
Internet Protocol Version 6 (IPv6)
– The new version of IP address which has more
capabilities than IPv4 in providing more IP
addresses.
– IPv6 uses a 128-bit address scheme allowing for a
total of 2128 addresses.
The Internet has experienced a phenomenal
increase of devices accessing the Internet.
• Because of this increase, IPv4 addresses are
running out.
The solution is for IPv6 to accommodate this
increased demand by providing a much larger
address space, along with improved traffic
routing and better security
• Larger IP address space - provide enough
address space for many decades to come
• Better security
• Better support for real time
• Includes Plug and play
• Better optimization
