About this network

A CoreSite network block (CORESITE-SPARE). CoreSite operates a US network of carrier-neutral data centers and interconnection campuses, now part of American Tower.

What it's used for

• Colocation, cross-connects, and interconnection for enterprises, carriers, and cloud on-ramps across major US metros.

Notable

• An IP in CoreSite space typically belongs to a colocation customer's equipment, not to CoreSite itself — the operator of whatever runs on it is the tenant.
• CoreSite announces from more than one ASN — see the sibling AS32184.

Interesting

• CoreSite's campuses host dense cloud on-ramps and interconnection fabrics, making them peering hubs in markets like Denver, LA, and Northern Virginia.
