Helpful tip for web server operators¹: if you want to know all of the network address space associated with a particular organization in a nice text form, find out their ASN (perhaps from https://bgp.tools/ with an IP address) and then:

whois -h whois.radb.net -- ' -i origin AS150436'

Dump that in a file, get all of the 'route:' entries, and feed them to your favorite CIDR/netblock calculator to minimize them and give you a nice list for your web server ACLs/etc.
