nxtdev.xyz is designed to be simple, but a few questions come up again and again. The answers below cover pricing, limits, DNS behaviour, and what happens in edge cases so you can get back to building.
Yes — completely free, no credit card required. Every account includes 2 subdomains and up to 100 DNS records per subdomain, and that free tier is not going away. There is no trial period and no hidden upgrade wall.
Records typically propagate globally in under 60 seconds. nxtdev.xyz manages DNS through Cloudflare’s authoritative network, so changes reach resolvers worldwide almost immediately. If a record does not appear right away, wait 60 seconds and run a propagation check from your dashboard.
Yes. The DNS infrastructure behind nxtdev.xyz is Cloudflare — the same network that powers millions of production sites. Your subdomain gets the same reliability and global performance as any Cloudflare-managed zone.
Each account can hold 2 base subdomains on the free tier. Each subdomain supports up to 100 DNS records, including A, AAAA, CNAME, TXT, MX, SRV, and delegated NS records combined. If you need more records, nameserver delegation gives you full external control without a per-record cap on your side.
No. Private address ranges are blocked on A and AAAA records for security reasons. This includes:
  • 10.0.0.0/8
  • 192.168.0.0/16
  • 172.16.0.0–172.31.255.255
Use a public IP address for your server. If you are testing locally, you do not need a public DNS record.
When a subdomain is suspended, all DNS changes and nameserver delegation are blocked. Existing records remain in place but cannot be modified. To appeal a suspension, email support@nxtdev.xyz with your subdomain and a brief explanation.
You can delete a subdomain at any time, and the slot frees up so you can claim a different label. However, the deleted label becomes immediately available for anyone else to claim — there is no reservation period. If the label matters to you, think carefully before deleting.
Nameserver delegation lets you point your subdomain’s DNS to an external provider — for example, your own BIND server or another DNS host. Once delegation is active, nxtdev.xyz defers all resolution for your subdomain to those nameservers, giving you full control over every record type and TTL. See Delegation overview for setup instructions.
While delegation is enabled, editing DNS records directly in the nxtdev.xyz dashboard is disabled. Remove delegation first if you want to switch back to managing records here.
nxtdev.xyz supports the following record types:
TypeCommon use
APoint to an IPv4 address
AAAAPoint to an IPv6 address
CNAMEAlias to Vercel, Netlify, Render, or any hostname
TXTSPF, DKIM, ownership verification tokens
MXMail exchange for self-hosted or managed email
SRVGame servers, XMPP, and custom protocols
NSNameserver delegation only
NS records are only accepted when you are setting up nameserver delegation at the apex of your base subdomain. You cannot add arbitrary NS records for other purposes.
