Meant ,I disconnect my DSL connection and ran the command again, this is the new outcome:

Ethernet adapter Neighborhood Place Connection:

Relationship-unique DNS Suffix . :

Observe in this situation, wherever I disconnected my link, you really don’t get a DNS server. This tells you that I am not related to the world-wide-web.

Also, observe the IP address begins with 192.168, which is the default tackle when your laptop is not related to the online.

One more command is the ping command. It will allow for to verify if a laptop or computer is linked to the community and completely ready to communicate, irrespective of whether intranet,

Reply from 216.109.118.66: bytes=32 time=35ms TTL=55

Reply from 216.109.118.66: bytes=32 time=39ms TTL=55

Ping data for 216.109.118.66:

Packets: Despatched = 4, Been given = 4, Shed = (% loss),

Approximate round excursion times in milli-seconds:

Minimum = 35ms, Maximum = 39ms, Common = 38ms.

That demonstrates that the host was reachable, and connected to the world wide web.

A extremely crucial command is the Nslookup. This will permit you verify if DNS (domain name server) is performing correctly. The functionality of the DNS server is to translate ip addresses to area identify of the networked laptop or computer. Listed here is an case in point:

C:> nslookup [http://www.yahoo.com]

Server: home5.bellatlantic.internet

Deal with: 151.198..39

Non-authoritative reply:

Name: [http://www.yahoo.akadns.net]

Addresses: 216.109.118.67

So, you enter the title just after Nslookup, it will give you IP addresses and vice versa.
