Microsoft Azure Traffic Manager

trafficmanager.net is the official domain for Microsoft Azure Traffic Manager, a DNS-based global traffic load balancer. This domain serves as the public-facing endpoint namespace for Azure customers configuring traffic distribution across their applications and services worldwide.

What Azure Traffic Manager Does

DNS-based load balancing - Routes client requests to optimal service endpoints based on configurable traffic-routing methods
Automatic failover - Monitors endpoint health and redirects traffic when endpoints become unavailable
Global distribution - Directs users to the lowest-latency endpoints for improved performance
Hybrid support - Works with both Azure-hosted and external (on-premises) endpoints

DNS Infrastructure

The domain uses Microsoft-operated nameservers with global distribution:

Nameserver	IPv4	IPv6
tm1.dns-tm.com	150.171.10.240	2603:1061:0:f00::f0
tm2.dns-tm.com	150.171.16.240	2620:1ec:8ec:f00::f0
tm1.edgedns-tm.info	13.107.222.240	2a01:111:4000:f00::f0
tm2.edgedns-tm.info	13.107.206.240	2620:1ec:bda:f00::f0

All nameserver IPs are hosted on Microsoft Corporation (AS8075) infrastructure across US and UK locations.

Technical Notes

No mail servers - The domain has no MX records (not used for email)
No DNSSEC - The zone is unsigned with no DS record in the parent zone
Massive subdomain usage - Parent domain for thousands of customer-configured Traffic Manager profiles (e.g.,myapp.trafficmanager.net)
