Часто задаваемые вопросы
Does this tool use a commercial API?
No. It uses server DNS functions or direct HTTP/HTTPS requests to the public target needed for the check.
Why can a valid check fail?
DNS can be temporarily unavailable, the target may block automated requests, shared hosting can restrict outbound networking, or the site may be offline.
Can this tool access localhost or private networks?
No. Tools that fetch websites block private, loopback, link-local and reserved IP ranges and restrict connections to standard web ports.
