Great!

Yes. Ping is not a NetBIOS utility. It is a TCP/IP utility.
You should have:
ipaddress FQDN
Ex.
130.57.4.70 novell.com
However:
130.57.4.70 novell
....will work.
To test:
ping novell
This is the response you get:
Ping request could not find host novell. Please check the name and try
again.
Why? Novell is an unknown and it is NOT a computer listed on this subnet.
Now add:
130.57.4.70 novell
....to your hosts file.
ping novell
This is the response you get:
Pinging novell [130.57.4.70] with 32 bytes of data:
Reply from 130.57.4.70: bytes=32 time=58ms TTL=45
If you then execute IE and put novell in the address bar, it will take you
to the novell.com site but in the address bar you will see:
http://novell/
not...
http://novell.com/
Why? Because your computer found an entry in the HOSTS file, which it
checks first prior to making a DNS request.
Can you still put in novell.com to get there?
Sure. This time it will convert to
http://www.novell.com/
Now, let's change the novell entry, in the HOSTS file, to:
127.0.0.1 novell.com
ping novell
The response you get is:
Ping request could not find host novell. Please check the name and try
again.
ping novell.com
The response you get is:
Pinging novell.com [127.0.0.1] with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128
Can I now not get to novell.com?
Sure. You can always use
www.novell.com because you are not blocking it and
there is a DNS entry for www.
If you're not running NetBIOS, and you do not have a HOSTS entry with a
single name, then you cannot ping it because TCP/IP requires a DNS entry to
resolve the name when a HOSTS entry does not exist. NetBIOS will allow you
to return a NetBIOS name if NetBIOS over TCP/IP is enabled.
So, what else did you learn here? If you want to block sites, you can put
them in your HOSTS file and point them to yourself. How is this helpful?
What if you put in your localhost address and the domain of an ad server?
You eliminate ad servers from being able to track you with embedded images
in email, store cookies on your computer, etc. You will still get the
relevant part of the email message but you they won't know it. However,
accepting text only messages does the same thing without all the extra work.
: 4. ipconfig /all returns two DNS addresses:
: 192.168.1.11 - which is the rouiter
: 194.98.0.1 - God knows where this one came from. Perhaps from my ISP (the
: router is also a ADSL modem and is connected to Internet). If it comes
from
: my computer settings, where should I look for it (ming I have DNS server
: obtain automatically)?
If your router is assigning IP addresses to client via DHCP, it may also be
passing DNS information. If you have Active Directory running on a server,
then you want the server to provide DHCP and DNS and not point to any ISP
DNS servers. If you only have clients (peer-peer) network, then using the
ISPs servers in this manner is what you want.
Don't forget to remove the novell entry from your HOSTS file. (O:=
