What is a VLAN (Virtual Local Area Network)?
A VLAN is a logical grouping of two or more servers which are not necessarily on the same physical network segment but which share the same IP network subnet. The advantage to passing traffic across a VLAN versus a LAN is that information on one VLAN can only be seen on that VLAN, and not by every server on the entire LAN. This is especially beneficial when you have many different nodes on a network sharing information with each other, and not every server is owned by the same customer as is the case with IRS Hosting. It allows us to provide our customers with more secure inter-server communication.
