These addresses are not enough for the increasing number of new devices like computers, smart phones, TVs, smart watches, cars and so on. Already\u00a0 more than 4.1 billion computing online devices are using IP addresses and that\u2019s why soon there will be shortage of IPv4 addresses.<\/p>\n<p>As we know IPv4 is of 32 bits. So it can provide 2^32 IP addresses.<\/p>\n<p>2^32 = 4294967296<br \/>\n= 4.2 billion<\/p>\n<p>To overcome this limitation we have IPv6 Addresses.<\/p>\n<p>Let\u2019s see what is the capacity of <strong>IPv6 address<\/strong> system.<\/p>\n<p>IPv6 is of 128 bits.

If we are using IPv6 then there is no need of NAT &amp; a packet can be traced from ultimate source to ultimate destination.<\/p>\n<p><strong>IPv6<\/strong> will allow better control of how heavy media and critical apps perform on a network, and allow faster. A new field is included in the IPv6 packet header-\u2018Flow Label\u2019- which keeps track of path and flow .IPv6 can give better support to services like VoIP &amp; video webcast, because it enhances quality of service (QoS).\u00a0 QoS permits certain types of network traffic, to get priority during heavy bandwidth use.<\/p>\n<p>With the exponential growth of smartphones, tablets and other internet-enabled devices, ISPs have started realizing the impact of IPv4 address exhaustion \u2014 and thus, some ISPs are truly started to switch over to IPv6.<\/p>\n<p>In India, IPv6 is already implemented &amp; tested in <a href=\"https:\/\/www.esds.co.in\/our-datacenter\"><strong>ESDS Data Center<\/strong><\/a>.
