Domain Hosting Checker

Last updated:

Find out where any domain is hosted. We resolve the IP, read the reverse DNS and ASN, and identify the hosting provider, DNS provider, and mail provider in one clean report.

Enter a domain to check hosting:

How the Checker Works

  1. Resolve the domain, A and AAAA records reveal the server IP.
  2. Look up the network, ASN and organisation identify the host.
  3. Read DNS and mail, nameservers and MX records are parsed.
  4. Summarise, you get host, DNS, and mail providers at a glance.

Why It Matters

  • Migration planning, know the current setup before you move.
  • Competitor research, see what infrastructure others use.
  • Troubleshooting, confirm where requests actually land.
  • Verification, check that a move or DNS change took effect.

Untangling hosting, DNS, and mail across providers can get messy fast. Our website maintenance services consolidate and document your setup so moves and fixes stay clean.

DNS Record Types Reference

A hosting lookup reads several DNS record types to piece together where a domain lives. Here is what each record does and a typical example value, so you can read the results with confidence.

Record Purpose Example
AMaps a hostname to an IPv4 address, the server that answers web requests.93.184.216.34
AAAAMaps a hostname to an IPv6 address, the IPv6 equivalent of an A record.2606:2800:220:1:248:1893:25c8:1946
CNAMEAliases one hostname to another, common for CDNs and platform connections.www → example.com
MXLists the mail servers that accept email for the domain, with a priority value.10 mail.example.com
TXTHolds text values such as SPF, DKIM, DMARC, and domain verification tokens.v=spf1 include:_spf.example.com ~all
NSNames the authoritative nameservers, which reveal the DNS provider.ns1.example-dns.com
SOAStart of Authority, holds zone metadata such as the primary nameserver and serial.ns1.example-dns.com hostmaster.example.com
CAASpecifies which certificate authorities may issue SSL certificates for the domain.0 issue "letsencrypt.org"

Domain Hosting Checker: FAQ

What does the Domain Hosting Checker return?
It queries public A, AAAA, NS, and MX records, selects the first returned IP for network lookup, attempts IPv4 reverse DNS, and reports public address lists, PTR name, organization, ASN, approximate IP location, nameservers, inferred DNS provider, mail exchangers, and inferred mail provider.
How is the hosting organization identified?
The endpoint sends the selected public IP to ipapi.co and displays its organization or ASN organization. This identifies the network announcing or serving that IP, which can be a host, cloud platform, ISP, CDN, or reverse proxy rather than the company operating the website.
Why does the result show a CDN instead of the origin host?
A proxied domain publishes the CDN or edge addresses to the public DNS. The checker can report only that public network and does not attempt to bypass the proxy or reveal a hidden origin. Treat a CDN result as an accurate view of the exposed delivery layer.
How are DNS and mail providers inferred?
The tool matches nameserver and MX hostnames against a fixed list of recognizable provider patterns. A known pattern produces a provider label; an unknown, white-label, or custom hostname can return no label. The raw NS and MX records remain the more reliable evidence.
Why are multiple IPs listed but details describe only one?
All returned A and AAAA values are listed, but ASN, organization, location, and reverse-DNS enrichment use the first IPv4 address, or the first IPv6 address when no IPv4 value exists. Geo-distributed and load-balanced domains can return other networks from other locations.
Why can reverse DNS be blank?
The implementation attempts a PTR lookup only for the first IPv4 address. The address owner may publish no PTR, or the domain may resolve only to IPv6. Missing reverse DNS does not mean the website or forward DNS is broken.
What should I verify before using this result for a migration?
Confirm all current A, AAAA, CNAME, NS, and MX records at the authoritative provider, document CDN and proxy settings, and repeat lookups from relevant regions. Do not change mail or nameserver records based only on an inferred provider label.
What data is sent during a hosting lookup?
The public domain is sent to the Web Aloha API. The server queries Cloudflare DNS-over-HTTPS and sends one resolved public IP to ipapi.co for network metadata. Private hosts are blocked, no credentials are requested, and the endpoint contains no application-storage step for the lookup.
