There are two key things here.
- All mobile operators use NAT, which means that several phones can share the same external IP at the same time. For example, operator O1 in location L1 might give 1 IP to 10 phones, while in location L2 it could be 1 IP for 100 phones. Depends on how greedy the operator is, their policies, the region, all that. For you as a user, it’s not a problem at all -- it won’t get you banned, but it can sometimes show up as a bad score on IP checkers.
- Like it already said above -- these IP scoring sites are kinda like weather forecasts
Not a single one of them knows for sure how flagged your IP really is. They just mash together a bunch of signals with their own logic. A high (or low) score on some site doesn’t mean anything by itself. Facebook, Insta and all those guys have their own fancy internal scoring -- and let’s be real, they’ve got way more resources than any of these checker tools.
So yeah, in your case, I’d just chill. It’s fine. You’re not gonna get banned because of that.
Of course, those scores can spook proxy buyers. But for the extra sensitive ones, you can just sell them ports from at&t.
