Georgia · network infrastructure

Atlanta holds the state's recorded capacity almost by itself. Digital Realty ATL13 counts 189 networks, ATL14 counts 77, CoreSite AT1 69 and Equinix AT1 61, with QTS Atlanta-Metro at 22 and EdgeConneX Atlanta at 12. Outside the city limits the counts fall away. QTS Atlanta-Suwanee has 11 networks, Centersquare in Lithia Springs 8 and CoreSite AT2 in Marietta 7. Networks meet locally rather than routing out of the state, with Digital Realty Atlanta at 148 participants and CIX-ATL at 117.

A Georgia IP address reflects a record the operator published, not where a machine physically stands. Geolocation databases read the address registration on the block and inherit whatever the operator entered. Mobile networks blur the picture further. AT&T, Verizon and T-Mobile aggregate subscriber traffic behind regional gateways, so a handset elsewhere in the state often presents an address that databases place in Atlanta, and sometimes one they place outside Georgia.

The origin ASN on the specific prefix answers more than a state label. Query the address, read which ASN announces it and check the netname registered on the block. Verizon holds seven mobile ASNs, and AT&T and T-Mobile five each, so a mobile address resolves to a carrier well before it resolves to a city. Georgia's 583 network presences and 322 peering networks describe facility inventory, which is a different measure from subscriber location.
