Langsung aja ya…. 
Sesuai judulnya, karena saya masih nubie dalam hal jaringan komputer jadi taunya cuma beberapa perintah aja…. 
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.
pertama : perintah dasar, hanya ping saja. command : ping [spasi] alamat tujuan (dalam hal ini ping ke IP Address)
C:\documents and settings\saptadihandoko>cd\
C:\>ping 127.0.0.1
Pinging 127.0.0.1 with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Ping statistics for 127.0.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
contoh kedua : perintah dasar, hanya ping saja. command : ping [spasi] alamat tujuan (dalam hal ini ping ke website)
C:\>ping www.yahoo.com
Pinging www-real.wa1.b.yahoo.com [209.131.36.158] with 32 bytes of data:

contoh ketiga : ping dengan diakhiri “-t”. command : ping [spasi] alamat tujuan [spasi] -t. bertujuan untuk melakukan pengetesan koneksi secara terus menerus. Apabila ingin diakhiri tekan ctrl+C.
C:\>ping 127.0.0.1 -t

Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
Control-C
^C
contoh keempat : ping diakhiri dengan “-l”. command : ping [spasi] alamat tujuan [spasi] -l [spasi] ukuran byte. Bertujuan untuk melakukan koneksi ke alamat tujuan dengan mengganti jumlah paket data yg dikirimkan. paket bisa diubah antara 0-65500 byte. perubahannya biasa terjadi pada time hasil ping.
C:\>ping www.yahoo.com -l 1024
