Awesome, bookmarked! Would it be possible to list all announced IP ranges for an AS?
You can use https://bgp.tools for that (e.g. https://bgp.tools/as/200676#prefixes)

#52From where do you get your geolocation information? I've been using the free MaxMind GeoLite2 databases and the GeoIP2 Python API for this kind of thing, but for a lot of IP addresses that I'd like to map, I can only get down to the country (and even some of those seem suspect). Is there any rate limit for queries?
How big is the MaxMind database ?

Reverse DNS lookups are usually pretty quick: ```shell > time dig +short -x 2600:dead::beef customer.my-isp.net. dig +short -x 2600:dead::beef 0.00s user 0.01s system 1% cpu 0.882 total ```
Reverse DNS does not give you all the hostnames that can point to a particular IP address though.
Other than brute forcing, I don't think anything does — that's the beauty and the curse of a proper federated system :)

In fact, it might not even give you any names that point to an IP address, since it might be out of sync with the forward system, especially if the records are built by hand.

#57Showing the start/ending address as part of the network would be helpful when looking up the network. That would avoid having to pull out a CIDR calculator when using this tool.

I have yet to see a geo-ip address for my IP that shows me even on the correct side of the country. I wouldn't trust this information as far as you can throw it ... and I've had this IP address for nearly 6 years now.

#60Nice,
I currently do "curl ipinfo.io" which returns json, and seems to use a more accurate geo lookup (based on the hotel wifi I'm currently on). It doesn't report the network though, and the ASN is a string of asn and name, no org or country, so that's a bonus.
However
curl ip.guide
