Network Very Slow Problem, please help

各位電腦界 C Hing, 有個 Network 問題,
Ping intranet IP is OK (1ms to 15ms),
But if I ping DNS, time 係 三位數 至 四位數,
最高係 4865ms.......
I wonder WHY..Thankls........

**Router and Switch have been checnge two times

1. Which ISP?
2. Try 直插 電腦到 BB Modem 唔經 router, isolate 左問題係 router 定 network 度先
3. Capture 個 'TRACERT WWW.HKIX.NET' 睇下

正常PING INTRANET 應該大係1ms 到咋喎...
除非個intranet 係好大....

仲有冇其他原因

如果內聯ping over 1ms嘅話,多數係條lan cable嘅問題~
