VLAN to Subnet Mappings

This is a copy of the spreadsheet Infrastructure uses to keep track of VLANs and subnets. It's unwieldy to look at and we can't verify that all descriptions and notes are still accurate. For most information you need on VLANs and their subnet mappings, consult our documentation on switchport configurations for a condensed table: Reconfiguring Switchports
