Anyone else noticing a lot of ips that start with 100 lately? What’s up with that? or Why are so many

Those ips that start with 100 are part of RFC 6598 (shared address space).

They’re legit, used for large-scale NAT by ISPs. No need to panic, but if you’re seeing them where you shouldn’t, might wanna check for misconfigs.

ip2location.com is handy for checking ranges.
