speed up web resolver and manipulating speed test

Unbound adalah alternatif DNS resolver dan juga DNS server, Unbound lebih aman dan lebih cepat dalam melakukan resolving ke domain atau juga dalam melakukan query. Unbound bisa di pakai di warnet, dan jaringan internal kantor atau juga sekolah (sebagai jaringan intranet). Unbound bisa juga bisa di bundle dengan squid proxy server, sebagai dns filtering, dan juga bisa di gunakan untuk manipulasi speedtest.

install dns unbound debian linux :

apt-get install unbound

 Konfigurasi untuk unbound , /etc/unbound/unbound.conf :

    interface: 0.0.0.0
    access-control: 0.0.0.0/0 allow
    access-control: 10.0.0.0/16 allow
    verbosity: 1
    local-zone: "labts.com" static
    local-data: "labts.com IN A 192.168.1.198"
    local-data: "www.labts.com IN A 192.168.1.198"
    local-data-ptr: "192.168.1.198 www.labts.com"
    #manipulasi speedtest
    local-data: "speedtest.indosatm2.com IN A 192.168.1.198"
    local-data: "speedtest.sby.dnet.net.id IN A 192.168.1.198"
    local-data: "speedtest.biznetnetworks.com IN A 192.168.1.198"
    local-data: "jogja.speedtest.telkomspeedy.com IN A 192.168.1.198"
    local-data: "www.speedtest.mygreenlinks.net IN A 192.168.1.198"

Test di pc client masing-masing, jangan lupa untuk setiap client memakai dns lokal 192.168.1.198 dan mapping semua ip speedtest dan uji kecepatan speedtest di client :p :

C:\Users\Aspire>nslookup
