Q 1. What are the major advantages of IPv6 over the version IPv4? 1. Extended Address Availability
Internet Protocol version 4 address have around4billionsaddresses. Depletion of IPv4 started in 2011. Then Internet Protocol version 6was designed to tackle the problems of address space and a number of related tasks. The updated IP addressing type IPv6, also called (IP Next Generation, which) will extend IP addresses from 32 bits to 128 bits and expand the number of available IP addresses to enormous 3.4 x 1038 or 340,000,000,000,000,000,000,000,000,000,000,000,000.
It was determined that the IPv6 address space will be distributed by IANA «Internet Assigned Numbers Authority - Commission for the standard number of the Internet [RFC-1881]»

Besides the obvious advantages in expanding the address space, the following advantages of IPv6 over IPv4:
In Fact, almost all the benefits of IPv6 are derived precisely from its packet format and addressing form. Reworked and improved standards will implement at the level of a strong cryptographic protocol (encryption) and many services such as QoS (Quality of Service). QoS support in IPv6 entirely at the network layer. This is extremely important for multimedia broadcasts. Changes made in the IPv6 indicate that he does not just solve the basic problem of a lack of address space, and rebuild the entire structure of the Internet so that it would be more logical and well thought-out. Also, the new protocol has possibility ofautomaticalconfiguration IP addresses for the target computers in the network in two ways: c via DHCP or improved without it.
In IPv6 packets can not be fragmented by routers and collected. The sender is obliged to find out in advance the maximum packet size (Maximum Transmission Unit, MTU), supported all the way to the recipient, and, if necessary, carry out on its own fragmentation. It stipulated that MTU can not be less than 576 bytes; probably in the next version of the specification is the value of IPv6 will increase up to 1500 bytes. Removal from the router worry about fragmentation also increases the efficiency of their work, though a bit complicated to some extent, performance and functionality of end

It was under the second PC's IP will be initialized to the online resources. In this case the IP can be both static and dynamic - according to the contract between the owners and the LAN service provider.

Another noteworthy point: theoretically the IP, when something is static for a particular PC, often begins to be used as a dynamic - and vice versa. The fact that both types of IP-addresses have exactly the same structure, which, looks like a «», where instead of 192 can be any three digit number. Static and dynamic IP-addresses are completely interchangeable and technologically identical. The difference between them, so it is very small and limited to one feature - the turnover when reconnecting to your ISP or LAN router.

Benefits if “Dynamic” IP
1. Much affordable than static
