Help with ip connection.. is phone hacked?

[sandybox]

Sorry in advance for my ignorance.. the app I use as a firewall NoRoot Firewall shows me the phone apps below wanting to contact this ip address: 203.207.157.116 port 47005. A lookup of this address shows its going to Korea. It worries me because the app names show it contains very specific and private information of my phone. Thanks for any light on this.
