Yeah, I've noticed ips that start with 100 popping up a lot lately too. Did some digging and found out they're part of the private IP range (100.64.0.0/10).
They're usually used by ISPs for carrier-grade NAT, so nothing to worry about. But if you're seeing them in weird places, maybe check your firewall logs.
Tools like whois or ipinfo.io can help trace them.
