Studying for W2KPro - DNS Question.
|
|
| Michael Patten 2002-12-11, 6:23 am |
| Hi,
In my notes for W2KPro, it says that if I don't have a DNS server on my
network to use IP address 192.168.1.203 or 192.168.1.205 in the DNS
field(s).
I understand that the 192.168.*.* subnet is a locally reserved range.
What I would like to know is, is there a list of the reserved addresses
(such as 192.168.1.203 reserved for DNS) available anywhere on the internet?
or are these IP's not internally used and are being used purely as
"Examples"??
I look forward to your feedback!

Michael Patten

The following addresses are reserved for private use:
10.x.x.x
172.16.x.x - 172.31.x.x
192.168.x.x
they are not used in the internet.

| I knew of 10.*.*.* and 192.168.*.*
Does anyone know what the addresses are reserved for?
(I am now assuming that the one listed in my book was for "example" purposes
only.)

| meaning that they are reserved means that they cannot be used on the internet. A packet with a 10.x.x.x IP would be dropped by Internet routers for example. | |
|
| BTW, don't forget the 169.254.x.x /16 Ip range now reserved for Microsoft's APIPA or Automatic Private Ip addressing... pretty cool setup. | |

| You are getting partial answers from several different posts:
10.x.x.x, 172.16.x.x - 172.31.x.x, 169.254.x.x & 192.168.x.x are all
considered Private Class IP address ranges.
They have been reserved as private so as not to waste the limited number of
public IP addresses that are left. Anybody in the world can use these
private class IP addresses on their private network (I am typing from a
computer with the private class IP address of 192.168.1.225). The numbers
that you cited in your example for the DNS servers are not set in stone.
Meaning you can assign any IP address that you want for your DNS
servers...you just have to configure the rest of the computers on your
network with the IP addresses of the DNS servers.
Public IP's are only need for publically accessible computers, such as web
servers, public routers, public DNS servers (like your ISP would host). At
home or in small networks you really only need one public IP address and the
rest of the computers can "borrow" that one IP address and connect out to
the Internet...but that is for another day.
Hope this was helpful.

| Thankyou TrainSignal... Much more helpful than the other posts.
Just as I suspected - the only reason they were using it in the example was
so as to be consistent through the book... and using am IP address in a
private IP Address range.
Thank you for clarifying this with me - feel much more confident in my train
of thoughts!
By "Borrowing" I'm assuming you are talking about a Proxy setup?
Good Idea, lets not discuss that!
