Infrastructure and operations
DNS
| Entity/system | Function | Entry point |
|---|---|---|
| Root Server System | Distributed service for the DNS root, operated by multiple independent organizations | root-servers.org |
| DNS-OARC | DNS operations, analysis, research, and community coordination | dns-oarc.net |
The familiar 13 root-server letters are logical identifiers, not merely 13 physical machines; deployments are distributed globally.
Interconnection and exchange points
| Directory/community | Function | Entry point |
|---|---|---|
| PeeringDB | Participant-maintained records for networks, facilities, and IXPs | Advanced Search |
| Euro-IX | IXP association and public IXP directory | IXP list |
| IX-F | Common schema for IXPs to publish operational data | ix-f.net |
These sources are complementary. They are excellent discovery tools but are not guaranteed to contain every network, facility, session, or current commercial relationship.
Routing visibility and operations
| Entity/system | Function | Entry point |
|---|---|---|
| Route Views | Public BGP collectors and routing archives | Collectors |
| RIPE RIS | Distributed routing collectors and data services | RIS |
| NANOG | North American operator knowledge-sharing community | nanog.org |
Collector data shows what participating vantage points observe; it is not a complete ground truth of every route or traffic path.
Physical connectivity
| Source | Function | Entry point |
|---|---|---|
| TeleGeography Submarine Cable Map | Discovery map for cable systems and landing points | submarinecablemap.com |
| TeleGeography | Specialist telecom research and network maps | Network maps |
Cable ownership, construction, ready-for-service dates, outages, and landing-station details change. Use the map to find candidates, then corroborate with cable-system operators, landing parties, regulators, and current filings.
