See an IP’s reverse DNS or the addresses a domain resolves to.
Example: 8.8.8.8 uzmantescil.com.tr
It shows the reverse DNS (PTR) of an IP, or the IPv4 and IPv6 addresses a domain resolves to. PTR is the record from the address back to a name. Missing PTR on a mail server is a common reason messages land in spam.
Several addresses usually mean a CDN or a load balancer. One address can still be a single server or an anycast point. This tool does not invent a city. It stays with the resolved addresses and the PTR.
An A record goes from the name to the IP. PTR goes from the IP back to a name. If they do not agree, mail identity is weak. A website does not need PTR. A server that sends mail practically does. PTR is set by the host that owns the address, not by an A record in your own zone.
The PTR name for an IP, or the IPv4 and IPv6 addresses for a domain.
It supports the identity of a sending mail server. Filters penalize a missing PTR.
Yes. CDNs and load balancers publish more than one A or AAAA record.
Only the network that owns the address can. A PTR in your own zone does nothing if the IP is not yours.
Whois shows the registrant. This tool shows the resolved address. They are different data.
