-* __IPs indexOf__ – Blocked IP is searched by `indexOf`
-* __IPs binary__  – Blocked IP is searched by binary search. For some reason miss time slightly increased.
-* __IPs switch__  – Simply `switch(Blocked_IP) { case1: ... caseN: return true }`. Works even better than binary search. Magic.
-* __Hosts switch__ – Radix trie built on `switch`. Comparable to __IPs switch__.
