 VLANs (Virtual Local Area Networks) have long been a primary means of virtualizing data center networks and are still in virtually all existing networks today. VLANs work by tagging a Layer-2 isolation domain with a 12-bit identifier ranging from 1-4094 that is inserted into a packet header that enables a logical grouping of a single or multiple subnets of both IPv4 and IPv6. It is very common for network operators to separate traffic using VLANs based on a subnet(s) function or security profile such as `web`, `db` or any other isolation needs.
 
-It is very common to have a compute host requirement of running multiple virtual networks concurrently on a host. Linux networking has long supported VLAN tagging, also known by it's standard 802.1q, for maintaining datapath isolation between networks. The Ethernet link connected to a Docker host can be configured to support the 802.1q VLAN IDs, by creating Linux sub-interfaces, each one dedicated to a unique VLAN ID.
