Setting IP di linux

Gan, saya punya dedicated server dengan 1 IP address. Nah minggu lalu saya tambah 5 IP lagi trus add lewat webmin. Hasilnya gini

Spoiler for "ifconfig -a":

[root@serv ~]# ifconfig -a

Masalahnya ada beberapa IP yang gak bisa di ping dari lokasi tertentu. Salah satunya xxx.117.138.122.
Saya ping dari beberapa lokasi lewat http://just-ping.com/hampir setengah dari daftar list gak bisa ping (100% lost), sedangkan IP xxx.117.138.132 semuanya bisa nge ping dan gak ada lost padahal keduanya berada di server yang sama.

Mohon pencerahan para master
