November 5, 2022What's your go-to for finding IP address information?
I like ipinfo.io for getting full ISP data. Sometimes they have business/organizational records attributed that ipinfo will show you, if the ISP had designated as much detail. Also sometimes if you have a large netblock, the ISP may also have provided a smaller netblock designation for that IP within their greater netblock that ipinfo will show you, but other tools wouldn't. I then use something like shodan or binaryedge to look at the whole netblock to see if any sort of certain business/industry/operation may be attributed to it. More on reddit.com

June 26, 2019What is reverse DNS lookup?
A reverse domain name system (DNS) lookup, or reverse IP lookup, is the opposite sequence of a DNS lookup. It's essentially a reverse IP tracker. With a standard DNS lookup online, you query the DNS server or hostname to get the IP address. But with the reverse DNS lookup command, you query the IPv4 address or IPv6 address to find the hostname. Therefore, when entering the IP address into the reverse lookup tool, it tests PTR records, allowing users can locate the domain name associated with the corresponding IP.

How does reverse DNS lookup work?
A reverse DNS lookup searches DNS queries for PTR records, or DNS pointer records. A PTR record maps an IP address to the hostname, so if there is no PTR record for DNS on the server, a reverse DNS record lookup won't work.

IP addresses function very much like the addresses written on an envelope of traditional snail mail. Every time you go to a website it's likely that your source IP address (the address on your packets) is logged by that website. Each IP address is in turn in a database that says who owns it, be it a datacenter, a business, or an ISP. IP addresses can also be associated with DNS names, like Reddit or another website. All of this information can be easily looked up if you know where to look. If you come to my website I can see your source IP Address instantly. With your IP address I can very quickly look up which country you are in, what ISP you are using, and if that IP is associated with a website, a business, or email. It's fairly trivial. An IP address though doesn't necessarily represent a specific person, in the same way that a phone call from a business or a house could be from anyone in that home or business.
