What are key features of IPv4 versus IPv6?
Differences between IPv4 and IPv6
| IPv4 | IPv6 |
|---|---|
| IPv4 has a 32-bit address length | IPv6 has a 128-bit address length |
| It Supports Manual and DHCP address configuration | It supports Auto and renumbering address configuration |
| In IPv4 end to end, connection integrity is Unachievable | In IPv6 end to end, connection integrity is Achievable |
What are the features of IPv6?
IPv6 – Features
- Larger Address Space. In contrast to IPv4, IPv6 uses 4 times more bits to address a device on the Internet.
- Simplified Header.
- End-to-end Connectivity.
- Auto-configuration.
- Faster Forwarding/Routing.
- IPSec.
- No Broadcast.
- Anycast Support.
Which features has improved in IPv6 compared to IPv4?
6 advantages of IPv6 to IPv4
- Simpler header format. IPv4 offers 12 header fields whereas IPv6 offers 8 header fields.
- More efficient routing.
- More security.
- True Quality of Service.
- Easier file-sharing.
- No more NAT (Network Address Translation)
What are four benefits of IPv6 over IPv4?
Six Benefits Of IPv6
- More Efficient Routing. IPv6 reduces the size of routing tables and makes routing more efficient and hierarchical.
- More Efficient Packet Processing.
- Directed Data Flows.
- Simplified Network Configuration.
- Support For New Services.
- Security.
What are the advantages and disadvantages of IPv6 and IPv4?
Advantages of IPv6 over IPv4
| Why IPv6? | IPv4 |
|---|---|
| IPv6 has improved security features | Security is dependent on applications – IPv4 was not designed with security in mind. |
| IPv6 has improved mobility capabilities | Relatively constrained network topologies restrict mobility and interoperability capabilities in the IPv4 Internet. |
Which are the features present in IPv4 and not in IPv6 *?
Explanation: An IPv6 address is 128 bits long. Therefore, 2128 i.e. 340 undecillion addresses are possible in IPv6. IPv4 has only 4 billion possible addresses and IPv6 would be a brilliant alternative in case IPv4 runs out of possible new addresses.
What are the advantages and disadvantages of IPV4 and IPv6?
Advantages of IPV4: IPV4 is necessary to encrypt data to ensure privacy. It takes security measures to encrypt data in its address packets. IPV6 protocol can be easily supported by most of the topology drawings. Since addresses are combined more effectively the process of routing has become more efficient in IPV4.
What are the advantages and disadvantages of IPv6?
IPv6 Design
- Pro: Much Larger Address Space.
- Pro: Virtually Unlimited Host Addresses per Prefix.
- Pro: Stateless Autoconfig.
- Con: Harder to Fit Prefixes on Topology Drawings.
- Draw: No More IP Scanning.
- Con: Don’t Forget to Enable IPv6 Routing.
- Pro: Automatic Link-Local Addressing.
- Con: Typing Long Addresses.
Which statement about IPv4 and IPv6 addresses are true?
Solution(By Examveda Team) IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format.
Why is IPv6 preferred over IPv4 Mcq?
IPv6 has an address space of 128 bits (which is 4 times larger than IPv4) and can accommodate large no. of devices. It is one of the major reason why IPv6 is preferred over IPv4 but the question is , Is having a larger address space suffice to prefer IPv6 over IPv4?
Why is IPv6 preferred over IPv4?
IPv6 (Internet Protocol version 6) is the next version after IPv4. Instead of the 32 bits used by IPv4 for addressing, IPv6 uses 128 bits for the same purpose – which theoretically makes it possible to assign 2 128 addresses – hence, it offers long term solutions to most of the problems that emerged while using IPv4.
What are four benefits of IPv6 over IPV4?
What is the speed difference between IPV4 and IPv6?
Web and cloud services provider, Akamai, measured the speed of IPv6 vs. IPv4. They found, “Sites load 5% faster in median and 15% faster for the 95% percentile on IPv6 compared to IPv4.” That means for some people who are pursuing high speed, IPv6 is indeed a better choice.
Which among the following features is present in IPv6 but not in IPv4 *?
anycast address
5. Which among the following features is present in IPv6 but not in IPv4? Explanation: There is an anycast address in IPv6 which allows sending messages to a group of devices but not all devices in a network. Anycast address is not standardized in IPv4.
How to convert an address from IPv4 to IPv6?
Built-in Quality of Service (QoS).
Which is better IPv4 or IPv6?
– Packet sniffing: Hackers can observe your IP traffic, in a practice known as sniffing, to find out sensitive information about you such as your online banking activity. – Surveillance: Your ISP, snoops, and even governments can spy on your web traffic. – Geo-blocking: Websites can see your location and discriminate against you based on it.
What does an IPv4 and IPv6 address look like?
Unlike the familiar IPv4 addresses which are 32 bits long, written in decimal, and separated by periods, IPv6 addresses are 128 bits long, written in hexadecimal, and separated by colons. An example would be: 3ffe:1900:4545:3:200:f8ff:fe21:67cf Colons separate 16-bit fields.
What address types are supported by IPv6?
You work as a Network Administrator for ABC Inc. The company has a Windows Server 2008- based network.
