Lookup AS by IP?

[trekzavier]

Hey, great package! Is there a way to look up IPs by AS? There is as-ip-blocks, but you have to already know the AS. Is there anyway to find out the AS by the IP address? Similar to when I type IP into https://lens.ipverse.net/ and it returns the AS along with additional data. Thank you for any information!

Hi, this it not planned at the moment but you could always write an offline-ish CLI to reverse the data. Here's an example: https://github.com/ipverse/tools/tree/master/ip2as

Thanks for the link. I actually tried creating my own script doing that exactly. But loading all of the AS entries takes a lot of memory and crashes my computer. I don't need every entry, just the ones from the IP's I look up. Is there any other way?

It‘s a lot of data. You can trade speed for RAM usage but would have to come up with some custom sort/filter logic.

Oh okay. I was hoping there would be some easier API. Oh well. thanks anyway
