| Limits | - per-object-cap (binding) 1 subdomain on a default account, up to 5 in total after GitHub star verification source
- retention-clamped a registration lasts 365 days and must be renewed in the final 60 days, with a 7-day grace period after expiry source
- request-rate after a successful registration the user waits one hour before creating another subdomain source
|
|---|
| Binding | per-object-cap the allowance of 1 subdomain, or 5 after a star, binds first; the 365-day renewal is the clock; the zone is delegable but the suffix is not on the Public Suffix List, so providers and the Let's Encrypt count treat all isroot names as one site |
|---|
| Identity | email a GitHub account, through the only sign-in the application supports, and a CAPTCHA on sign-up and on each registration; no phone and no card are named in the guide |
|---|
| Egress | no query cap published |
|---|
| Per-object cap | 1 subdomain on a default account and up to 5 in total when GitHub star verified; one registration per hour |
|---|
| Retention | a registration lasts 365 days; renewal opens 60 days before expiry and adds 365 days; an expired registration can still be renewed during a 7-day grace period (365 days) |
|---|
| Interface | unknown a web dashboard for registration, DNS records, nameservers, renewal and deletion; no API was read |
|---|
| Tooling | the isroot dashboard, then a host that takes a DNS record |
|---|
| Composes with | the dashboard has an Edit Nameservers action, so the name can be delegated to an external DNS provider that accepts the exact zone; isroot.in is not on the Public Suffix List, so some providers refuse the zone and the TLS limit is shared with every other isroot subdomain |
|---|
| Reliability | a name expires after 365 days unless renewed; the suffix is not on the Public Suffix List, so some DNS providers or hosts may refuse the zone and sibling registrations share a site boundary |
|---|
| Notes | Binds: 1 subdomain (5 with a star) and a 365-day renewal, with a 7-day grace period. The zone is delegable, but the suffix is not listed, so some DNS providers refuse the zone, and every isroot name draws on one Let's Encrypt count of 50 certificates in 7 days for isroot.in. The listing status is stated by the vendor's guide; the shared count is an inference. |
|---|
| Evidence note | documented the getting-started, limits, manage-domains and provider-compatibility pages were read and quoted; the terms and the dashboard were not read; the shared TLS count is an inference from the vendor's Public Suffix List status and the Let's Encrypt registered-domain rule |
