Best Practices for IP Whitelisting – How Do You Manage It? or IP Whitelisting: How Strict Should Your

"IP Whitelisting – What’s Your Go-To Approach?"

Hey folks,

So, ip whitelisting... love it or hate it, it’s still a thing. But how do y’all actually manage it without losing your minds?

I’ve seen teams go full lockdown—only a handful of IPs allowed, zero flexibility. Others just slap on a /16 subnet and call it a day (risky much?).

Personally, I lean toward a middle ground. Whitelist the essentials, but keep a backup auth method for emergencies. And *please* document your rules—nothing worse than inheriting a mess of unlabeled IPs.

What’s your move? Super strict? Chill? Or do you think ip whitelisting is just outdated now?

(Also, how many times have you accidentally locked yourself out? Be honest.)
