# Domain & DNS – Complete Guide for Hosting & Game Servers

Domain & DNS explained: nameservers, A/MX/TXT/SRV records, Cloudflare, SPF/DKIM/DMARC & Minecraft SRV – everything for hosting & game servers.

**Quick answer:** Domain & DNS are the foundation of every website, email and game server. Here you'll find the complete knowledge base – from DNS records (A, MX, TXT, SRV) to nameservers, Cloudflare, SPF/DKIM/DMARC and Minecraft SRV records.

Whether you're connecting a website, setting up email or making a Minecraft server reachable via domain – these guides cover everything. NexoraHost offers unlimited DNS records with no artificial limits.

## Frequently Asked Questions

### My domain won't connect – what should I do?

Check in this order: nameservers set correctly? A record points to correct IP? DNS propagation waited (15–60 min)? With Cloudflare: check proxy status (orange cloud). Details in our [nameserver guide](/en/domain/nameserver).

### How do I set up email for my domain?

Set MX record to mail server, then add SPF, DKIM and DMARC as TXT records. Our [email DNS guide](/en/domain/spf-dkim-dmarc) explains each step with examples.

### Can I reach my game server via domain?

Yes – with an A record (direct IP) or SRV record (port + domain). For Minecraft we recommend SRV records so players don't need to enter a port. Guide: [Minecraft SRV record](/en/domain/minecraft-srv-record).

### DNS propagation takes forever – is that normal?

With TTL 3600, 15–60 minutes is normal. If it takes longer than 48 hours, there's usually a configuration error (wrong nameservers, typo in record). Lower TTL to 300 before changes to speed up future updates.
