I was thinking back to an earlier post, about AT&T’s 3G coverage. This time around, I finally had a choice to go with Verizon. It’s LTE, which is a better technology (and AT&T’s LTE is probably similar, but there isn’t LTE in Seattle for AT&T.) Here’s the results for my new Verizon LTE iPad (ignore where it says iPhone. I’m using the same app on both the iPhone and iPad, but it’s not a universal app.)
Verizon LTE
For comparison, I went back and tested my iPhone again, now with a new 4G icon. The last time I did this, just about two years ago, I was about half a mile away from where I’m at now. Two years, and half a mile closer to Seattle, and I get this.

I’m starting a new job where I need to have my SSH keys pushed to hundreds of Red Hat servers. The special sauce is a command called ssh-copy-id.

When I need to find an open IP, this is a decent way to do it. I wish there were a way to find IPs that don’t respond, but this works for now. This won’t work if your network bans ICMP traffic, or your host doesn’t respond, but is alive.
If you want to extract the IPs from your output, you can use this SED statement
sed -n 's/^.*[^0-9]\([0-9]*\.[0-9]*\.[0-9]*\.[0-9]*\).*$/\1/p'
