What is Anycast DNS and why does it matter?

Anycast DNS makes one DNS address available from many locations. Each user query is routed to the nearest healthy node, which can improve response times and keeps one location issue from stopping the service. ADG operates more than 30 Anycast nodes across regions.

What does 99.999% DNS SLA mean in practice?

A 99.999% SLA is a target that allows roughly five minutes of unplanned downtime in a year. It is supported by redundant Anycast nodes, health monitoring, and automatic failover; the exact commitment is defined in the service agreement.

What is DNSSEC and do I need it for my TLD?

DNSSEC adds cryptographic signatures to DNS data so resolvers can verify that an answer is genuine. This helps reduce the risk of forged DNS answers. Every new gTLD registry must support DNSSEC; ADG helps manage signing, keys, and the operational process.

How does ADG protect against DDoS attacks on DNS?

ADG's Anycast network offers up to 1 Tbps of backbone-level DDoS mitigation capacity. Per-client capacity and protection limits follow the selected configuration and service agreement.

Can ADG provide DNS for both gTLDs and ccTLDs?

Yes. ADG's managed DNS can support gTLDs and ccTLDs. ADG has cleared ICANN's Main RSP evaluation; DNS and additional-service scope are confirmed against each requirement and agreement.

THE FOUNDATION OF DIGITAL ACCESS

When DNS works well, people simply reach your service.

Every visit to a website, app, API, or domain service starts with DNS. When DNS is slow or unavailable, people may fail to connect even when the application itself is running. That makes DNS part of customer experience and business continuity, not just background infrastructure.

ADG operates an Anycast DNS network with more than 30 points of presence across 6 continents. Queries are routed to healthy locations close to users, while DDoS mitigation, DNSSEC, and 24/7 monitoring help your team keep services available and trusted.

CORE CAPABILITIES

Protection and control behind every resolution.

Built for teams that need services to remain reachable, understand what is happening, and act quickly when conditions change.

DNS closer to your users

Our Anycast network routes queries to the nearest healthy node. That means faster responses for users and continued service when one location has an issue.

30+ Anycast nodes worldwide
Redundancy across 6 continents
Automatic failover between nodes
Routing that accounts for latency

Built-in DDoS protection

An attack should not make your domain disappear from the internet. Layered defences help absorb and filter harmful traffic before it disrupts DNS resolution.

1 Tbps backbone absorption capacity
Automatic detection and mitigation
Protection for network and application traffic
Real-time traffic filtering

DNSSEC managed with discipline

DNSSEC helps users reach authentic DNS answers, not forged ones. We handle signing and key lifecycles so your team is not burdened by repetitive, error-prone work.

Automated KSK and ZSK rotation
DS record lifecycle management
Support for algorithm changes
DNSSEC activation and operations

Visibility and response around the clock

We monitor availability, query performance, and security events so issues can be identified early—before they become a disruption your users feel.

Real-time query analytics
Anomaly detection and alerting
99.999% uptime SLA tracking
24/7 incident response readiness

FOR TEAMS THAT CANNOT COMPROMISE

When your domain must always be found.
