It seems many companies in Korea disable ICMP
Even big korean search engine www.naver.com I can't ping to it

ing- ging all dayOldman pinging ha ha ha
i would leave it on, and rate limit it.
I don't think there is really a huge difference in the % of block compared to rest of world
It seems like naver is utilizing a different network (Akamai) for outside of Korea. Most South Korean companies do block ICMP for some reasons.
(Kakao and Daum are same companies (merged) so they should might have same server configuration though)
I mean.. Azure cloud drops ICMP to all their VMs by default, I think AWS ELBs do too, etc
Disabling ICMP is extremely important. It is possible to do something called RCE (remote code execution) via pinging a server.
Ou, tell us more about this.
I am sorry, but I am not allowed to talk about specifics. It was discovered by the Russian FSB and is an exploit used by many state actors.
