Reverse DNS
| Reverse DNS | crawl-66-249-66-1.googlebot.com |
|---|---|
| Forward-confirmed | Yes: the name points back to this address |
How we check: we look up the address's reverse DNS name, then look up that name and see whether it points back to the same address.
Location
| Registered in | United States (US) from the registry's postal address (an estimate) |
|---|---|
| City | Not available: we don't use a geolocation database for other people's addresses. |
Domains on this IP
Many websites can share one address (CDNs, shared hosting), so blocking an address can block sites you didn't mean to. We don't keep a list of the domains on an address.
Check it elsewhere
These services have their own data and terms. We only link to them: the address is sent to them only if you click.
JSON and command line
curl -s "https://iplover.com/api/check/66.249.66.1?lang=en"What this means and where the data comes from
What the findings mean
Reverse DNS
The name points back to this same address, so whoever runs the network really set it up. Large services such as Google and Bing use this to prove their crawlers are genuine.
Network type
An estimate from the network owner's name (Google LLC). Names can mislead, and many providers serve homes, phones and businesses on the same network.
Location
This is the country where the block is registered. It can differ from where the address is actually used.
Abuse contact
To report spam, scanning or attacks from this address, write to this contact with the exact times (and time zone) and your log lines. It belongs to the network owner, not to iplover.
Network range
CIDR is the size of the block: /24 means 256 addresses. The smaller the number after the slash, the bigger the block.

Notes and limitations
No source is complete. “No sign of abuse” means none of the sources listed at iplover.com/sources matched; it is not a guarantee.
The network type describes the network, not the person. A VPN, proxy, Tor, hosting or mobile address is not a sign of abuse, and no IP address shows who someone is or exactly where they are.
We cover abuse blocklists, network type and registry data. We don't scan for malware: for antivirus verdicts, check VirusTotal.
