North Carolina · network infrastructure

North Carolina's capacity is spread thin across many buildings. Charlotte holds the most, with Digital Realty at 113 N Myers St counting 14 networks, CENTRA CLT01 at 8, CLT2 at 7 and a second Digital Realty address at 6, alongside three Flexential and TierPoint sites in single figures. Durham follows with CyrusOne NC-1 and TierPoint RTP, Morrisville has Flexential Raleigh, and Asheville has ERC Broadband and DartPoints AVL1. All three exchanges sit in Charlotte, so networks elsewhere in the state carry traffic to the city or out of it to peer.

A North Carolina address in a geolocation database comes from the record an operator published for the block, not from a measurement of the device. Registrations follow company paperwork, so a network with racks in Charlotte can file addresses to the state while the users behind them connect from far away. Mobile networks stretch the link further. AT&T, T-Mobile and Verizon concentrate subscriber sessions behind regional gateways, so a handset connected in Durham can present an address that databases place in another state.

The prefix carries better evidence than a city label. Read the origin ASN on the route and the netname on the block. A route originating from a carrier mobile ASN, such as 19540 for AT&T or 12079 for Verizon, points to a national pool where the state field reflects a registration rather than a location. North Carolina's 90 facility presences and 13 exchange participants describe where networks interconnect, and they say nothing about which addresses land in which town.
