Website hosting checker: who hosts this website?

Find out who is hosting any website. Enter a site. We read its DNS, network and response headers and name the hosting company, the CDN, the server software, the mail provider and the WordPress theme, builder and plugins we can see.

Why it matters who hosts a site

Copy what works, skip what does not

Before you buy hosting, check the sites you admire in your niche. If three fast Indian blogs sit on the same host, that is a better signal than any sponsored list. If a slow site sits on a host you are considering, that is worth knowing too.

Know your own stack

Inherited a site from a developer or an agency? This tells you where it lives, where the DNS is managed, who handles the email and which cache, SEO and builder plugins load on the front end, without logging in anywhere.

How we tell

Four public signals, read in order of reliability, plus the home page HTML.

Show the records and headers we look for (technical)

NS ns1.dns-parking.comNameservers

Hostinger, SiteGround, Bluehost, GoDaddy, WP Engine and WordPress.com all hand out their own nameservers. A match here is near certain.

x-hcdn, x-kinsta-cache, x-wpe-*, x-acHost headers

Managed hosts sign every response. Hostinger CDN, Kinsta, WP Engine, WordPress.com, Flywheel, Rocket.net and WPX each have one.

AS47583 HOSTINGERNetwork (ASN)

Every public address belongs to a network. We ask the free Team Cymru DNS service which one; a cloud name (DigitalOcean, AWS) means a VPS or a host like Cloudways on top.

PTR srv123.hstgr.cloudReverse DNS

The server’s own name often carries the host’s brand. Weakest signal, because resellers rent these servers too.

server: cloudflareCloudflare in front

The address, network and reverse DNS belong to Cloudflare, so the host has to be read from nameservers, cookies and other headers.

/wp-content/themes/kadence/WordPress stack

Theme folder, child theme, Elementor or another builder, the cache plugin, the SEO plugin, WooCommerce and a generator tag with the version.

Hosting checker: FAQ

How do I find out who hosts a website?

Enter the address above. We read its nameservers, network owner (ASN), reverse DNS and response headers, then name the host with a confidence level and the evidence. By hand, an NS lookup plus the site’s response headers gets you most of the way.

Why does it say Cloudflare?

Cloudflare sits in front of many sites, so the address you see belongs to Cloudflare. We then rely on the nameservers and host headers; if those are hidden too, the real host cannot be seen from outside.

Is the result always right?

No. High confidence means a host-specific header or nameserver matched. Medium or low means only the network matched, for example a cloud that many managed hosts run on.

Does the check change anything on the site?

No. It reads public DNS and one public page, tries no login and stores nothing.

Can it see the WordPress theme and plugins?

Only what loads on the home page: the theme, page builder, cache and SEO plugins whose files or HTML comments are public.
