Whois lookup

Whois\n In short, it is a database used to query whether a domain has already been registered and the detailed information of a registered domain (such as the domain owner, the domain registrar, the registration date and the expiry date). Querying the domain's Whois server lets you look up the contact details of the domain's owner and the registration and expiry dates. You can use 350730.com/whois access!

Explanation of how domain expiry and deletion rules are applied:

International domain

(1) DNS resolution is suspended on the expiration day; if the domain is not renewed within 72 hours, its DNS is pointed to an advertising (parking) page. After expiration, the domain enters a 30-45 day redemption grace period (the exact time varies by registrar policy)

(2) After the grace period, the domain enters the redemption period (REDEMPTIONPERIOD, 30 days)

(3) After the redemption period, the domain enters a deletion period of about 5 days; then it becomes available for anyone to register.

Domestic domain

(1) Resolution is suspended on the expiry day; if it is not renewed within 72 hours, the domain's DNS is pointed at a parking page (ads). Auto-renewal is available within 35 days.

(2) 36-48 days after expiration it enters a 13-day premium redemption period, during which the domain cannot be managed.

(3) If still not renewed 48 days after expiry, the domain may be deleted at any time.

  2. 2Follow the prompt and read the specific items returned (status code, size, matched rule).
  3. 3Download the artefact and place it yourself, e.g. a favicon needs to sit at the site root and be declared with a link tag.

Frequently asked questions

The check looks cached

Most checks rely on public fetching, and the target may sit behind a CDN. Re-test later or compare nodes.

Is the ICP filing lookup accurate?

It comes from a public endpoint and can lag. The MIIT record is authoritative.

Why does the favicon not show on mobile?

Ship multiple sizes (or a PNG) and declare link rel="icon"; browser caching also delays the new icon.
