Does IPv6 use subnet mask?

IPv6 subnetting is easier than IPv4. IPv6 doesn’t have a subnet mask but instead calls it a Prefix Length, often shortened to “Prefix”. Prefix length and CIDR masking work similarly; The prefix length denotes how many bits of the address define the network in which it exists.

What is the IPv6 equivalent of the subnet mask?

255.0 means that the subnet is a range of IP addresses from 10.10. 10.0 – 10.10. 10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4.

What is subnet in IP address?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs.

What exactly is a subnet?

A subnet, or subnetwork, is a network inside a network. Subnets make networks more efficient. Through subnetting, network traffic can travel a shorter distance without passing through unnecessary routers to reach its destination.

Why am I getting an IPv6 address?

Why is my IPv6 Address showing instead of my IPv4? The real short answer is because and IP v6 address is an IP address and the website you used shows the actually used IP address. That answers the question in the title, now moving on to what you really wanted answered.

Does IPv6 require a subnet mask?

IPv6 does not use subnet masks but does have a means of indicating subnets that is similar to CIDR. IPv6 routing is based on a prefix length as well where the prefix length represents the bits that have fixed values or are the bits of the network identifier.

Why is IPv6 replacing IPv4?

IPv6 is more advanced and has better features compared to IPv4. It has the capability to provide an infinite number of addresses. It is replacing IPv4 to accommodate the growing number of networks worldwide and help solve the IP address exhaustion problem. IPv6 was developed by the Internet Engineering Task Force (IETF).

What is an advantage of using IPv6?

Advantages of IPv6 Efficient Routing. In IPv6 the size of the routing table is reduced to an extent that hierarchical address allocation is created for providing efficient routing. Increased Capacity. Since IPv6 is based on 128 bit addressing scheme, it provides more address space compared to a standard IPv4 addressing. Directed Addressing. No Subnetting. Security.

Is IPv4 more commonly used than IPv6?

The main reason IPv4 is still more widely used than IPv6 is because it takes a lot of time and resources for the transition from one to the other. After all, it’s quite costly and time consuming to upgrade all the routers, servers and switches that rely on IPv4.
