## No-IP

- `domains-dns/no-ip-free` | qualifies-with-caveat | evidence documented | binding retention-clamped | category free dynamic DNS hostname | tier Free Dynamic DNS
- needs card no, phone no, ID no, institution no | verified 2026-11-03T16:43:07.606Z (live) | stale on 2026-12-04
- url https://www.noip.com/free
- free tier: 1 hostname on a No-IP shared domain, no credit card; the hostname must be confirmed every 30 days or it is deleted | unit: objects | metered on: object-count | read on: 2026-11-03 | source: [1]
- per-object cap: 1 hostname on the free plan, on one of 30+ No-IP shared domains; the zone belongs to No-IP, so the user holds no record count of its own; hostnames may be type A, AAAA or Port 80 Redirect | source: [1]
- retention: a free hostname is active for 23 days, may be confirmed in the next 7 days, stops resolving when it expires, sits 14 more days in redemption and is then deleted and open to anyone; an update from a client does not confirm it | days: 30 | source: [2] | note: confirmation is a web login or an e-mailed link
- egress: no DNS query cap published on the pages read | metered: no | source: [1]
- identity: email | detail: the sign-up form asks for an e-mail address and a password and a terms checkbox that states one free account; the free page says no credit card is required (https://www.noip.com/sign-up, https://www.noip.com/free); no phone field in the captured form text
- interface: rest
- limits:
  - retention-clamped (binding): confirm every 30 days: active 23 days, 7-day confirmation window, 14-day redemption, then deletion [2]
  - per-object-cap: 1 hostname on the free plan [1]
- binding note: the 30-day manual confirmation is what decides; an update client keeps the address current but does not renew the hostname
- interface detail: a dyndns2-style HTTP update request, GET https://dynupdate.no-ip.com/nic/update?hostname=HOST&myip=IP with HTTP Basic auth (the account e-mail address and password), on port 443 over HTTPS or on ports 80 and 8245 over HTTP; the response is a text code such as good, nochg or badauth; the pages read list a RESTful API only under the contact-sales Branded Remote Access plan
- tooling: the free No-IP Dynamic Update Client for Windows, macOS and Linux, any dyndns2-compatible client or router, and curl from cron; confirmation itself is a web or e-mail action with no documented API
- composes with: a name for a changing address and nothing else on the free plan; the domains are No-IP's, so the name cannot be a zone of its own, and the 30-day confirmation has to be done by hand
- reliability: a free hostname silently stops resolving if the 30-day confirmation is missed; the update endpoint answers HTTP 401 with the body badauth for a request without credentials; a client without an approved User-Agent can be rate-limited or blocked, and the badagent and abuse codes tell a client to stop updating
- notes: Free confirmation interval: 30 days (23 active, 7 to confirm, then 14 in redemption). The paid Enhanced plan, USD 2.50 a month billed annually for 5 hostnames, lists hostnames that never expire.
- evidence note: the free-plan page, the confirmation knowledge-base page, the FAQ, the sign-up page and the update protocol pages were read and quoted; the unauthenticated update endpoint was probed once and answered 401 badauth
