Question 1. What Is Ipv4?
IPv4 stands for Internet Protocol version four. It is the fundamental era that makes it feasible for us to attach our devices to the Internet. Whenever a device accesses the Internet it's far assigned a completely unique, numerical IP address which include 126.96.36.199. To send information from one laptop to some other via the Internet, a facts packet should be transferred across the network containing the IP addresses of each the sender and the receiver. Without IP addresses it isn't feasible for gadgets to talk with each different. It is fundamental to the existence of the Internet.
Question 2. Why Are We Running Out Of Ipv4 Addresses?
IPv4 makes use of 32 bits to cope with computer systems on the Internet. That way it may help 2^32 IP addresses in general -- around 4.29 billion. In the 1980’s a 4 billion computer systems at the Internet appeared like impossibility. Surprisingly, nearly all four.29 billion IP addresses have now been assigned to numerous establishments, main to the disaster we are facing nowadays. We have now not totally run out of these addresses however with the growing population and the ever growing range of gadgets that connect to the Internet, the day whilst we will completely exhaust these addresses may be very close to. Hence the need to shift to a system that gives a larger addresses space.

Question four. What Is The Address Format Of Ipv4?
Address Format: Dotted Decimal Notation: 192.149.252.Seventy six
Question five. What Is The Prefix Notation Of Ipv4?
Prefix Notation : 192.149.0.Zero/24

Question 6. What Is The Main Limitation Of Ipv4?
The biggest limitation of IPv4 is its 32-bit addressing area resulting in approximately four.3 billion IP addresses most effective. The fast growth of internet, wi-fi subscribers and deployment of NGN technology is main to extended consumption of IP addresses with the result that IPv4 addresses are almost exhausted these days.
Question 7. Is Ipv6 Backward Compatible With Ipv4?
IPv6 is not backward like minded with IPv4. These protocols can't talk to each other without delay.

Question eight. Is It Possible To Have An Ipv4 And An Ipv6 Addresses Simultaneously?
Yes. Most of the operative structures that presently aid IPv6 allow the simultaneous use of each protocols. This manner, the communication with IPv4 only networks in addition to IPv6 only networks is feasible, and the use of the applications designed for each protocols.
Question nine. What Does “ipv4 Depletion” Mean?
It approach that the valuable pool of to be had IPv4 addresses managed via the IANA is empty. As of February 2011, most of the 4 billion IPv4 addresses to be had had been allocated to be used or reserved for a specific technical cause.

Question 10. Will The Internet Still Work When There Are No Ipv4 Addresses Left?
Yes. The Internet will keep to paintings and the IPv4 addresses already in use will hold to feature.

Question 11. Why Can’t We Just Make More Ipv4 Addresses?
IPv4 permits for a most of just over four billion unique addresses (as an instance: 10.142.131.235). It is limited by way of the quantity of specific quantity combinations that may be created in this format.

Question 12. Can I Still Get Ipv4 Address Space From My Rir?
As lengthy because the RIRs still have to be had IPv4 address space, they'll preserve to distribute it in accordance with their regional guidelines.
We cannot expect how lengthy every RIR’s pool of IPv4 cope with area will remaining.

Question 13. I Am An Internet User. How Will Ipv4 Depletion Affect Me?
Internet users gained’t observe the effect of IPv4 depletion in the foreseeable future.
However, in the future there may be elements of the Internet which you cannot attain if the internet site or provider is an IPv6-best network and your Internet Service Provider (ISP) does no longer provide its customers with IPv6 addresses.
Question 14. Why Is Ipv4 Depletion Such A “hot Topic” When There Are Plenty Of Ipv6 Addresses That Can Be Used Instead?
IPv4 addresses and IPv6 addresses are not robotically like minded with each other, so community operators want to make investments to make sure that this will happen. Some community operators are not prioritizing the funding to make their software program and hardware IPv6-ready.
The RIRs and different enterprise companions are working hard to make certain that everyone is privy to IPv4 depletion and the importance of preparing for the huge adoption of IPv6 on the Internet.
Question 15. Will Ipv4 Address Depletion Mean That Services Will Get Switched Off?
No. Both IPv4 and IPv6 will run in parallel until there's not any want to do so.
Basic C Interview Questions
Question 16. How Long Do You Think We Will Have The Ipv4 And Ipv6 Protocols Active At The Same Time?
No one will placed a date on whilst IPv4 can be grew to become off. This will rely on marketplace forces. When IPv6 will become the dominant community it'll draw more human beings in and much less humans will worry about IPv4. There will usually be backwards compatibility for such things as older network printers that cannot transition to IPv6.
Question 17. I Run An Isp With A Block Of Ipv4 Address Space. Can I Just Convert That Into Ipv6 Space?
You will want to gain new IPv6 addresses in addition in your present IPv4 deal with blocks. IPv4 address area that you have today can nevertheless be utilized in a dual IPv4-IPv6 environment. The RIRs all have rules that make it truthful for an ISP with IPv4 space to use for and acquire IPv6 address area. You need to touch the RIR to your region or your ISP for more information on how to accumulate IPv6 addresses.
It will also be excellent idea to use this possibility to remodel your addressing plan, taking gain of the greater flexibility of IPv6 to assign subscriber address blocks greater optimally. Similarly, client sites may additionally use IPv6 as an possibility to remodel and optimise their internal addressing plan. However, it is able to be feasible to re-use an present subnet addressing plan inside the new IPv6 block, if this is preferred.

Question 18. When Will I Need To Turn Off Ipv4?
Possibly never. The reason of deploying IPv6 is to make certain network increase and persisted interconnectivity whilst IPv4 cope with area becomes depleted and tough to reap. In addition, as the worldwide Internet keeps to extend, it is in all likelihood that a few Internet websites will simplest be available thru IPv6.
To keep away from problems, one ought to be absolutely IPv6-enabled by the time IPv6-best web sites start performing. However, in exercise, it's miles handiest the general public (or user) dealing with part of an organization's infrastructure that needs to be IPv6 enabled at the outset. The again-end infrastructure - which customers do not interact with directly - can stay based totally totally on IPv4, so long as this is the most price-effective method. (Enterprises may also determine that it is extra value-effective to gradually flip off IPv4 in parts in their community once it's far not needed or in huge use.)
One need to expect, however, that it'd never be price-powerful (or viable) to improve positive legacy structures. Thus, it's going to possibly be a decade or more earlier than agency web sites locate themselves in a function to keep in mind completely turning off IPv4. In practice, there's no want to show it off as long as IPv4-best programs nevertheless remain in use.

Question 19. How Do I Connect Ipv4 And Ipv6?
Click Network and Sharing Center for your computer. Click Local Area Connections after which click Properties to configure community addresses and different records. Click the Networking tab and then, click either Internet Protocol Version four (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) after which click Properties.
Question 20. How Do You Reset Ipv4 And Ipv6?
Type ” netsh winsock reset ” ( with out costs ) within the Command Prompt and press Enter.
Type netsh interface ipv4 reset in command prompt and press Enter.
Type netsh interface ipv6 reset in command spark off and press Enter.
Ipconfig /flushdns press Enter.
TCP/IP Interview Questions
Question 21. What Is The Difference Between Ipv4 And Ipv6?
The Internet Protocol version four (IPv4) is a protocol to be used on packet-switched Link Layer networks (e.G. Ethernet). IPv4 offers an addressing functionality of about 4.3 billion addresses. The Internet Protocol model 6 (IPv6) is greater superior and has better features as compared to IPv4.
Question 22. What Is Ipv6 Ipv4 Dual Stack?
One approach, referred to as dual stack, entails going for walks IPv4 and IPv6 at the same time. End nodes and routers/switches run both protocols, and if IPv6 communication is possible this is the preferred protocol. A common twin-stack migration strategy is to make the transition from the middle to the threshold.
