WHAT'S NEW · v7.24.71-stable

Control your DNS from any AI agent

A new MCP tool server lets Claude Code, Codex, Copilot, Antigravity and other AI agents manage domains and DNS records for you — from any device on your local network, using the exact same login and permissions as the dashboard.

🔒 LAN-only, same as the rest of NexoralDNS — the MCP server never talks to the public internet.

PROTOCOL SUPPORT

DNS Protocol Expansion

NexoralDNS now speaks all three major DNS transports — plain UDP, reliable TCP, and encrypted TLS — with zero configuration changes.

📡UDP :53Classic
🔗TCP :53New
🔒TLS :853New

DNS over TCP

NEW
Port 53 TCP · RFC 1035 §4.2.2 · RFC 7766

Full TCP transport for DNS — required for responses over 512 bytes, DNSSEC chains, and zone transfers. Handles 2-byte length-prefix framing automatically.

▸Large response support — DNSSEC, TXT, many-answer records
▸RFC 7766 idle timeout — 30s keepalive, auto-disconnects stale clients
▸Singleton architecture — shared single-flight cache across connections
▸Zero-config startup — starts alongside UDP automatically
test
dig +tcp google.com @10.x.x.x

DNS over TLS

NEW
Port 853 · RFC 7858 · DoT

Encrypted DNS transport using TLS 1.2+ to prevent eavesdropping and spoofing. A self-signed certificate is auto-generated via openssl on first boot.

▸TLS 1.2+ enforced — TLS 1.3 preferred per RFC 7858 §3.1
▸Auto cert generation — self-signed via openssl, saved to /etc/nexoral/cert
▸Shared across restarts — cert persisted on disk
▸Same 7-layer pipeline — identical block, cache & upstream logic
test
kdig -p 853 @10.x.x.x +tls google.com

All three transports share the same 7-layer query processor, Redis cache, block-list engine, and analytics pipeline — consistent behaviour regardless of how a client connects.
