Disini hanya beberapa yang akan saya jelaskan.
Beberapa perintah yang akan dibahas antara lain adalah ping, tracert, nslookup dan telnet.- Ping
Ping berguna untuk melakukan pengetesan koneksi kearah IP tujuan
dengan mengirimkan paket-paket data. Ping ini menggunakan protokol ICMP
(Internet Control Message Protocol), dan pada OSI berada dilayer 3
(Datalink Layer). Perintah pada ping dapat dilihat dibawah ini.
