What the IP lookup shows
- IP addresses: the domain's A records (IPv4) and AAAA records (IPv6), the addresses a browser actually connects to. If a CNAME comes first, the tool shows the chain as well.
- Hostname (PTR): the reverse DNS record of the IP. It often reveals the hosting company, for example
static.….clients.your-server.defor Hetzner orvps-….vps.ovh.netfor OVH. Mail servers need a matching PTR, otherwise mail ends up in spam. - Name servers and mail servers: who manages the DNS zone and where email for the domain goes. For subdomains without their own zone, the tool asks one level up.
- Country, region, city: the location according to the geolocation database, plus whether the address is inside the EU. A good first answer to the GDPR question "where is my data?".
- Network operator and AS number: the autonomous system through which the address is reachable. The link opens Hurricane Electric's BGP overview with all networks of that operator.
How accurate is the location?
An IP address carries no location. Geolocation databases derive it from regional registry data (RIPE, ARIN …), routing information and measurements. The country is almost always right for server addresses. The city is an estimate: often it is the provider's headquarters or the nearest large data center, not where the server actually is. For mobile and DSL connections the city is frequently off by many kilometers.
CDN and anycast: If a website sits behind Cloudflare, Fastly or Akamai, the tool shows the CDN's address. These addresses are announced by dozens of data centers worldwide at the same time. The location shown is just a registration place, the actual web server stays hidden. The tool points this out for well-known providers.
Which other websites are on the same IP?
DNS cannot answer this question. It only translates in one direction, from names to addresses. An IP does not "know" which domains point to it, and a shared hosting server can carry hundreds. Services offering this collect DNS answers into huge databases over years, which makes them incomplete or paid. That is why myline.de deliberately does not offer it.
On your own server it is quick: list all Apache virtual hosts shows every domain with its IP. For the opposite direction, the hostname of an IP, see reverse DNS (PTR) lookup.
"My IP": what every server sees about you
The "My IP" button shows the address your request arrives from at myline.de. Every website you visit sees exactly this address. On mobile networks and many fiber connections, lots of customers share one address (carrier-grade NAT), and with a VPN you see the VPN server. For a server without a browser, use the one-liner get the server's public IP address.

- Look up the MX records of a domain
- Forward-confirm the reverse DNS of a mail server IP
- Check DNS propagation on several public resolvers
- Check whether a server IP is on the Spamhaus blocklist
Privacy and sources
The lookup runs on the myline.de server. Location and network operator come from a database stored there, and for the DNS records the server asks the responsible name servers, just like any ordinary page request. Your IP address is not passed on to anyone, no map services are embedded, and the domains and addresses you enter are not stored. To prevent abuse there is a limit of 30 lookups per hour, for which only an encrypted check value is kept briefly, never an IP address.
