just now i called 1300889515 for inquiry about wan ip we connected. Mr.Kuma, the person who answering my call told me that:
"if u want to play online games or downloading stuff without any problem or less delayed;timed out, u must dc & rc until u get ip 218.xxx. this is the only solution for those who facing high ping or timed out problem when they online gaming or downloading with ip 219.xxx & 60.xxx"

i said this is not fair to those who getting ip 219.xxx or 60.xxx, we all subscriber paid the same amount for a stable & reliable "fast" connection! but not for 50/50 who can achieve "fast" connection while the other left to death(slow connection). i start argue with him, why only ip 218.xxx less laggy issue? not all the ip have the same speed? he replyed back to me: "because u on dynamic ip not fixed ip, everytime u dc or rc, u'll get different ip"

he's not answer me correctly nor he don't know what i'm asking about?

in the end, he finally finished his fairy tale.
from the conversation above, i discovered what exactly he want to telling me is, "if u want a stable & reliable "fast" connection, get a fixed ip"

screw him!
