# DNS Overview

DNS

# Edge DNS

Enterprise-grade authoritative DNS with global anycast distribution, instant propagation,
and advanced features like geographic routing and ALIAS records.

## Key Features

### Global Anycast Network

DNS queries are automatically routed to the nearest point of presence for
ultra-low latency resolution worldwide.

### Instant Propagation

Changes propagate to all edge nodes within seconds. No more waiting for TTL expiration
or delayed updates.

### DDoS Protection

Built-in protection against DNS amplification attacks and query floods with
automatic rate limiting and filtering.

### Geographic Routing

Route traffic to different endpoints based on the geographic location of the
DNS resolver for optimal user experience.

## Architecture

Edge DNS uses a master/slave architecture for reliability and performance:

M
Master Server

Handles zone management, record updates, and API requests.
Pushes changes to all slave nodes in real-time via NATS messaging.

S
Slave Nodes

Distributed globally via anycast. Handle all DNS queries with local zone cache.
Report query metrics back to master for analytics.

## Supported Record Types

| Type | Description | Use Case |
| `A` | IPv4 address | Point domain to server IP |
| `AAAA` | IPv6 address | IPv6 connectivity |
| `CNAME` | Canonical name | Alias one domain to another |
| `ALIAS` | Apex CNAME alternative | Point root domain to another hostname |
| `MX` | Mail exchange | Email routing |
| `TXT` | Text record | SPF, DKIM, domain verification |
| `NS` | Name server | Delegate subdomains |
| `CAA` | Certification Authority Authorization | Control which CAs can issue certificates |
| `SRV` | Service record | Service discovery (SIP, XMPP, etc.) |
| `PTR` | Pointer record | Reverse DNS lookups |

## Metrics & Data Retention

Query metrics are collected and aggregated at multiple granularities:

Minute-level data 24 hours
Hourly aggregates 7 days
Daily aggregates 90 days
