Using ipinfo_3.3.1_windows_amd64.exe, I don't see any difference with summarize or without it. I think would be the actual syntax needed, but it throws an error: `ipinfo_3.3.1_windows_amd64 summarize bulk 206.195.68.21 137.119.131.80 err: POST https://ipinfo.io/summarize?cli=1: 422 { }` `ipinfo bulk 206.195.68.21 137.119.131.80 summarize` and `ipinfo bulk summarize 206.195.68.21 137.119.131.80` and `ipinfo bulk 206.195.68.21 137.119.131.80` all give the same output Embedded help says: `summarize get summarized data for a group of IPs.`
