Frequently asked questions
Quick answers about propagation, resolvers, and how this checker works.
Can DNS Checkers crawl my whole site? +
No. Link tools are intentionally limited in count and timeout to stay free and polite.
Do you fake PageRank? +
No. Google Toolbar PR is obsolete. We explain open metrics instead.
Are generated robots/htaccess files production-ready? +
They are starting points. Review before deploying to production servers.
Why block private IPs? +
To reduce SSRF abuse when fetching remote URLs or certificates.
Is domain check the same as buying a domain? +
No. It only inspects DNS presence, not registrar availability.
