What is a DMARC?
• A DMARC is short for “Demarcation” and creates a place
within a tenant’s leased space to connect their
communications equipment to the Port’s fiber optic
network
• This DMARC connection allows a tenant to ultimately gain
access to Internet and communications service providers

Tenant DMARCs are a landlord/tenant communication technology best practice
Why Do We Need DMARCs
• A large portion of Sea-Tac’s existing tenant
communications infrastructure is obsolete and outdated
• DMARCs facilitate a tenant’s connection to modern high-
speed fiber optic network cabling
• Will facilitate a tenant’s flexibility to adjust their telephone,
Internet, and data services to better meet business needs
• Allows quicker activation of communication service as
tenants move in

Many existing Sea-Tac tenants are still on old copper wiring and outdated cabling
