Should I use VLAN or subnet?

VLANs perceived to be more secure and provide more robust control for the network. Subnet has limited control in comparison to VLAN. VLAN is extremely flexible, it brings better work performance, less traffic, and more efficiency.

How do you subnet?

255.248 or /29.STEP 1: Convert to Binary.STEP 2: Calculate the Subnet Address. To calculate the IP Address Subnet you need to perform a bit-wise AND operation (1+1=1, 1+0 or 0+1 =0, 0+0=0) on the host IP address and subnet mask. … STEP 3: Find Host Range. … STEP 4: Calculate the Total Number of Subnets and Hosts Per Subnet.

How many IP addresses can a device have?

1.1. Each number can, technically, range from zero to 255. Routers differ from other computing devices in that they have (at least) two IP address: a public one and a private one. The public side of a router is visible on the Internet.

Can default gateway be on different subnet?

Regards. You cannot have a default gateway on a different subnet. The very first thing that your external NIC is going to do is send out an ARP broadcast for the MAC address of the default gateway. ARP is layer 2 and does not route.

Can two VLANs have the same IP address?

The OSA-Express Layer 2 implementation allows the hosts to manage IP addresses and ARP cache, so it is possible to have a single guest LAN segment (or VSWITCH segment) where two different hosts use the same IP Address on different VLAN groups. …

How assign IP address to VLAN?

Here are the steps to configure an IP address under VLAN 1:enter the VLAN 1 configuration mode with the interface vlan 1 global configuration command.assign an IP address with the ip address IP_ADDRESS SUBNET_MASK interface subcommand.enable the VLAN 1 interface with the no shutdown interface subcommand.More items…

How many VLANs should I have?

If you’ve got traffic that has to be prioritized(like VOIP, or Storage) than put that traffic in one VLAN. Your Users(and Printers) can be in one VLAN, or because of the amount I would make 2-3 VLANs; if there are security reasons to separate a certain department or group of users, than take them out of the User VLAN.

Do switches assign IP addresses?

But since the switch does not have the capability to assign IP addresses, the computers connected to it will not be able to communicate with each other. They will get an Automatic Private IP Address (APIPA). You need to assign a static IP address to your computers. Click here for instructions.

What happens if two devices have same IP address?

For a system to communicate via a network, it must have a unique IP address. Conflicts arise when two devices are on the same network trying to use the same IP address. When this occurs, both computers end up not being able to connect to network resources or perform other network operations.

How do I get multiple IP addresses?

The easiest way to get multiple IP addresses is to purchase them from your ISP, in a block. Alternately, you can use an internet service provider that frequently changes IP addresses, like a PPPoE based ISP.

Can different VLANs be on the same subnet?

No, VLANs don’t require different subnets. Different subnets require different subnet addresses if they ever need to be able to route and/or talk to each other) and by extension if one VLAN wants to talk to a different VLAN it must use different addresses so we can make a routing decision to the right place.

Can a device have multiple IP addresses?

Yes. All IP Routers (networking) are computers (hosts) with more than one IP Address. Even non-routers can have more than one IP address. Doesn’t even require additional physical NICs in the presence of virtual local area networks (VLAN).

Is a VLAN a subnet?

At a high level, subnets and VLANs are analogous in that they both deal with segmenting or partitioning a portion of the network. However, VLANs are data link layer (OSI layer 2) constructs, while subnets are network layer (OSI layer 3) IP constructs, and they address (no pun intended) different issues on a network.

What are three advantages of VLANs?

VLANs provide a number of advantages, such as ease of administration, confinement of broadcast domains, reduced broadcast traffic, and enforcement of security policies.

What is VLAN IP address?

Specifically, it is the IP address of the “switch” the VLAN is on. It doesn’t necessarily have to be the gateway IP for the VLAN but typically is since you typically setup IP addresses on the VLAN at the Layer 3 “router” for the VLAN and thus use this IP address for the gateway for clients on that VLAN.

Can different subnets talk to each other?

Devices in different subnets can communicate. That is the purpose of a router. Routers route packets between different networks. Even if devices in different networks are on the same layer-2 broadcast domain, you need a router to let the devices communicate at layer-3.

Can different VLANs communicate without a router?

No, they cannot. A router is must to communicate between different VLANs/networks. A L2 switch is enough if you want to transmit packets within a single VLAN. But, if there are multiple, then the VLANs need to be identified by each other which is done only by a router.
