How would I find all the IP ranges currently assigned to company X?
I need to know all the address ranges that my ISP can use for their - whatever needs. So I started with digging the domain name of one of their mailservers and fed the result to whois. I got a subnet (eg 220.127.116.11/16).
But! That company might have other ranges assigned. How would I find out? Thx
I'd start with that URL but put known IPs in there. You might be able to find other blocks the ISP owns by going up the hierarchy.
Well, in the meantime i found out that I am in the "ripe" zone (the subnet was just an example) and I've tried https://apps.db.ripe.net/search/query.html to find out more but I am seriously lost…
Im gonna read https://www.ripe.net/data-tools/support/documentation/ripe-database-user-manual-getting-started now.
sorry for pre-maturely asking about this. I just can't stop asking for help instead of putting some effort in reading about things...first! :P
