Is subnetting important for CCNA?

Is subnetting important for CCNA?

Subnetting is a really important topic, not just for passing the CCNA exam, but for networking in general. It’s one of the core knowledge areas that you need to understand if you’re going to work in networking.

How much subnetting is on the CCNA?

Cisco CCNA – Subnetting IP

What is IP address CCNA?

CCNA: IP Addressing. An IP address is a unique logical identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number, and represented as 4 decimal values of 8 bits each. The decimal values range from 0 to 255.

Is subnetting still relevant?

Yes, every day. It allows us to segment our network into smaller chunks to limit broadcast domains or to establish different security domains to isolate traffic from one another.

Is subnetting still used?

Remember, that even with the reduction of broadcasts, subnetting is still useful to further reduce unnecessary network traffic. It’s also important to remember to use subnetting for security purposes.

How do I find my CCNA Subnet Mask?

To determine the slash notation of the subnet mask, convert the dotted decimal format into binary, count the series of 1s, and add a slash on the start. For example, we have the dotted decimal subnet mask of 255.0. 0.0. In binary, it is 11111111.00000000.

Why subnetting is required?

Subnetting ensures that traffic destined for a device within a subnet stays in that subnet, which reduces congestion. Through strategic placement of subnets, you can help reduce your network’s load and more efficiently route traffic.

Is subnetting needed with IPv6?

So, the answer is – subnetting in IPv6 is still necessary, but not for the reasons IPv4 people are used to. You have a pre-defined number of available subnets to use, based on the /48 you’d get from your ISP, but you’ll have more than enough address space to work with.
