TI's xxx.mydns.telkomsa.net option provides ddns automatically when using your TI account. Problems arise when using multiple ISP accounts as TI only knows the last IP they assigned you thus the need for the services of 3rd party providers; DynDNS, No-IP, DtDNS and the like.
For some users who only have one concurrent connection, this can be an easy way of being able to access something on their network, without requiring support from their modem or installation of software on their devices or pay for additional services or change providers when changing modems.
Obviously, we can't know about seasions on other ISPs, and about the only way to do this without software support on the modem and configuration is to use the session information.
