Do VLANs have to have different IP addresses?
A VLAN (Virtual Local Area Network) is its own logically segregated broadcast domain. You assign networks, or subnets, just as you would with a physically separated broadcast domain. VLANs do not really have IP addresses assigned to them.
Can VLANs share a subnet?
VLANs use software to emulate separate physical LANs. Each VLAN is thus a separate broadcast domain and a separate network. As you have identified, routing between these VLANs would be difficult, because they are the same subnet.
How do I assign an IP address range to a 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.
How many IP addresses are in a VLAN?
512 IP addresses
The decimal subnet mask for a /23 is 255.255. 254.0. With it, you can get a single VLAN with 512 IP addresses.
How to find the IP address range of a specific VLAN?
04-15-2019 10:39 AM Just to add a little to what has already been said. To find the networks associated with a specific host, you can change that host to bit and mark the location of the mask. You should consider that the last IP of each range corresponds to the broadcast address of that network, so it cant be used to address any host.
Can a VLAN be used as an IP subnet?
04-15-2019 10:19 AM – The question does not correlate , a VLAN when it is being used as an ip-subnet can have ip address range (s) assigned provided the network manager (role) does a proper job. 04-15-2019 10:21 AM
Why are there so many hosts in a VLAN?
Importantly, network protocols like NetBEUI and IPX/SPX used a LOT of broadcasts for name resolution. Literally, every device would broadcast at regular intervals its protocol name and MAC address to other devices to hold a name/address table. Or they would respond to name resolution requests received by broadcast. 1
Can a network address be used to address any host?
You should consider that the last IP of each range corresponds to the broadcast address of that network, so it cant be used to address any host. 04-15-2019 10:19 AM 04-15-2019 10:19 AM
