Use the DNS Lookup tool to query any DNS record type — A, AAAA, MX, TXT, CNAME, NS, PTR, SOA — and understand what each record type does.

When a domain expires, its DNS records stop resolving. MX records vanish, email bounces, websites go offline, and authentication breaks. Recovery is possible during the grace and redemption periods, but fees increase and time is limited. This guide covers how to diagnose, recover, and prevent domain expiry.

A domain expiry warning means your domain's registration period is ending soon. While auto-renewal handles most cases, failed payments, locked accounts, and bounced billing emails cause domains to lapse every day. This guide covers what to check at each urgency level — from 90 days out to 7 days before expiry.

DNSSEC adds cryptographic signatures to DNS responses, letting validating resolvers confirm that answers have not been tampered with in transit. This guide covers the chain of trust, key types, how to enable signing, common failures, and how to verify your setup.

A domain that lapses takes everything with it — email, website, DNS records, authentication. This guide covers the expiry timeline from grace period through deletion, why auto-renewal is not foolproof, and how to monitor domain registration proactively.
