24 IPv4?

25 TCP/IP Has Been Built On Version 4 Of The Internet Protocol IPv4 – Used Since 1981 IPv4 Was Created When The Internet Was Just A Small Experimental Network. Considering Internet Growth & Change - Ipv4 Has Done Its Job Admirably. It Has Been Apparent For Many Years That Certain Limitations Of IPv4 Would Hold Back The Future Growth Of Both Internet Size And Services If Not Addressed. About IPv4 - 1

26 IPv4 Plays Key Role In Internet Replacing IPv4 Will Be A Major Endeavor The Necessary Changes Require Altering Nearly Everything In TCP/IP Operates. Replacing Ipv4 Is Necessary For Several Years, Development Of A New Version Of IP Has Been Underway, –Officially Called Internet Protocol Version 6 ( Ipv6 ) –Also Called IP Next Generation Or Ipng –IPv6 Is Poised To Take Over From Ipv4; It Will Be The Basis For The Internet Of The Future. About IPv4 - IPv6

27 Ipv6 Is Built Upon And Similar To Ipv4 IPv6 Performs The Same Functions As IPv4 –Addressing –Encapsulation –Fragmentation & Reassembly –Datagram Delivery & Routing Ipv6 Is Still Under Construction; It Continues To Change! –Changes Being Made To Both Ipv6 Standards And Implementation Every Month About IPv6
