Advantages of Subnet
- Subnetting divides the broadcast domain i.e., improves the speed, efficiency, and network performance.
- Reallocating IP addresses
- Reduce network congestion
- Improve network security
Difference Between VLAN and Subnet
The VLAN stands for Virtual Local Area networks and they are defined by 802.1q protocol (it’s a VLAN tagging protocol that allows the ethernet frame size to increase by four bytes due to the insertion of a four-byte VLAN tag into the ethernet frame). Using VLANs, we can virtually separate our LANs into smaller networks; they work like normal LANs except they are logically or virtually separated as opposed to physically.
There are a few reasons to use VLANs one of the main reasons is to broadcast traffic. VLANs give us all of the benefits of physically separating our network virtually without spending extra money on hardware. The traffic still behaves in the same way as if it was physically separated or split.
