Help center

Everything you need to register, connect and operate a LentsName domain. For more help, open a support ticket from your dashboard. Our target response time is 24 hours.

Getting started

Create an account, verify your email and use the dashboard to search for an available prefix. A standard account can hold ten active domains by default. Administrators may grant a custom allowance; VIP accounts have no domain-count limit.

DNS records

A DNS-mode domain may contain one A record, one AAAA record or one CNAME record. CNAME cannot coexist with A or AAAA. Private, loopback, link-local and reserved addresses are rejected.

One prefix can resolve through multiple enabled parent domains, such as example.i.letsname.net and example.v.3dns.net. Record changes apply to every hostname assigned to that prefix.

DNS changes normally propagate within 60 seconds. Use a dig query to confirm:

dig example.i.letsname.net A +short

Quick registration

From the home page, enter a public IPv4 or IPv6 address and choose Create instantly. LentsName generates a random 16-character alphanumeric prefix and immediately creates that hostname under every enabled parent domain.

Quick registrations are anonymous. They remain subject to the Acceptable Use Policy and may be suspended by an administrator.

URL forwarding

Forwarding mode is mutually exclusive with custom DNS records. Choose 301 for permanent updates and 302 for temporary destinations. Incoming path and query parameters are preserved.

Only HTTP and HTTPS destinations are accepted. Credentials in URLs, local addresses and unsafe redirect targets are blocked.

API

Create an API key from the Developer access section of your dashboard. Store it securely; the complete key is displayed only once.

Check availability:

curl -H "Authorization: Bearer lnt_live_…" https://www.letsname.net/api/v1/availability?prefix=nebula

Register IPv4:

curl -X POST https://www.letsname.net/api/v1/domains \
  -H "Authorization: Bearer lnt_live_…" \
  -H "Content-Type: application/json" \
  -d '{"prefix":"nebula","ipv4":"203.0.113.10"}'
  • 201: domain created and DNS provisioning started
  • 202: submitted to human review
  • 409: prefix unavailable or domain quota reached
  • 422: invalid prefix, IP or record configuration
  • 429: rate limit exceeded

Limits and quotas

Standard accounts receive ten domains by default. Administrators can override this value per user. Whenever a quota is lower than the existing domain count, current domains stay active but no additional domains can be created until the account is below the limit.

Deleting a domain starts a 30-day prefix cooldown.

Security

Administrators must use Google Authenticator or another TOTP-compatible app. API keys should have unique names and be revoked when no longer needed. LentsName never asks for your password by email.
