Overview

Certain system services in the terminal access external services, typically via specific IP ports.

Services List

Service	Domain Name or IPs	Description
TMS (wizarview)	www.wizarview.com	The major TMS servers: Ports_and_IP_Used_by_TMS
204 Pages	connectivitycheck.gstatic.com www.google.com www.qualcom.com	These servers are used to check internet connectivity by pinging an empty HTTP(S) page (204 response), and commonly use HTTP port 80 and HTTPS port 443. For example: http://connectivitycheck.gstatic.com/generate_204
A-GPS Location Services	location.services.mozilla.com locprod2-elb-us-west-2.prod.mozaws.net xtrapath2.xboxprod.izatcloud.net	The first two servers associated with the Micro-G project. The 3rd one server belonging to Qualcomm. TMS agent use these services for GPS data, which can be disabled through TMS agent configuration.
NTP Services	asia.pool.ntp.org (old default) cn.pool.ntp.org (old backup) hk.pool.ntp.org (old backup) 2.android.pool.ntp.org (new default from aosp)	The Android system utilizes these servers for automatic time adjustment when set to 'AutoTime', and typically uses UDP port 123 for time synchronization.
