IPv4 and IPv6
IPv6 is the new version of the internet address protocol that is gradually replacing IPv4. Do you think that IPv6 overcomes any issue of IPv4? If yes then explain your answer with proper reasoning (maximum 5 lines)
A concise, coherent and to the point comment is preferred over lengthy comment having irrelevant details. Your comment must not be more than 5 lines. Comments, posted on regular Lesson's MDB or sent through email will NOT be considered in any case. Any request about such an acceptance will not be catered.
Best of Luck!

IPv4 is the most widely deployed Internet protocol used to connect devices to the Internet. IPv4 uses a 32 - bit address scheme allowing for a total of 2^32 addresses (just over 4 billion addresses). With the growth of the internet it is expected that the number of unused IPv4 addresses will eventually run out because every device -- including computers, smartphones and game consoles -- that connects to the Internet requires an address.
IPv6 is the successor to Internet Protocol Version 4 (IPv4). It was designed as an evolutionary upgrade to the Internet Protocol and will, in fact, coexist with the older IPv4 for some time. IPv6 is designed to allow the Internet to grow steadily, both in terms of the number of hosts connected and the total amount of data traffic transmitted
My LMS can't open plz any other student that have same situation ??? plz check your lms and tell me because today is last date to submit gdb cs601. plz help
no it is not working..i am also facing the same problem
No it's not working ..
Don't worry students .. the said error will be solved after some time . and if it is not to date extend ho jaye gi all academic activities ki ..
so don't worry
The Difference Between IPv6 and IPv4 IP Addresses
An IP address is binary numbers but can be stored as text for human readers. For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. Each number can be zero to 255. For example, 126.96.36.199 could be an IP address.
IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons. An example IPv6 address could be written like this: 3ffe:1900:4545:3:200:f8ff:fe21:67cf
why IPv6 is overcome of IPv4:
IPv6 has 128-bit address space or 4 times more address bits than IPv4's 32-bit address space. In real terms, every residential or commercial customer will be able to receive more address space from TWC than the entire IPv4 address space contains – several billion IP addresses.IPv6 includes security in the underlying protocol. For example, encryption of packets (ESP: Encapsulated Security Payload) and authentication of the sender of packets (AH: Authentication Header).To implement better support for real-time traffic (such as videoconference), IPv6 includes a flow label mechanism so routers can more easily recognize where to send information.IPv6 includes plug and play, which is easier for novice users to connect their machines to the network. Essentially, configuration will happen automatically. IPv6 takes the best of what made IPv4 successful and gets rid of minor flaws and unused features.The header now has a fixed length of 40 bytes. Some header fields that were a part of IPv4 have been removed. They are discussed more in detail in the description of IPv6 header. This was done to improve on header processing time and forwarding techniques.support for data authentications and data security has been specified.packets belonging to the same traffic flow needing special handling or security can be labelled by the sender
