Any networking GURU here?

In wireless Router configurations, why all wireless routers are assigned
with either 192.168.1.1 or 192.168.0.1? Any input? [???1]

Its another set-standard meaning for the "localhost". Meaning that I.P. range such as 192.168.0.~. The reasons come from RFC 1918 action by Internet Assigned Numbers Authority(IANA) that reserved three blocks of I.P. addresses as "provate internets"

These includes ranges ...

10.0.0.0 through 10.255.255.255
172.16.0.0 through 172.31.255.255
192.168.0.0 through 192.168.255.255

I guess you fall into the third one.

Thanks Push! I got RFC1918 and RFC3330.
And also I found that IANA.org has helpful insights.

guru reporting. any other problems email or PM me.

actually IP address are cut into classes.

Class A, B, and C. for class A address you get roughly 16 million IP's or something wild like that, class A only have the first octet reserved, 10. Class B has less nodes per network, and class C less, leaving only the final octet for node addresses. furthermore subnets can break those down.


edit: i shouldn't have been so ignorant, there are class D and E address as well, but then we step into a different sector of IP addressing.

Yet oddly, despite RFC1918 Microsoft decided to auto assign class B addresses in the 169.254.0.0./16 subnet when DHCP is enabled on an adapter, but no DHCP server is available. Hmmm...

call your isp and ask them for a gateway address, ip address, and subnet mask.

That is an accepted standard and it is currently under revision:
http://www.ietf.org/internet-drafts/draft-ietf-zeroconf-ipv4-linklocal-10.txt

Subnetting is such a pain in the ass!

 

[BMWlover]

There are many network experts here!! Subnetting is almost always troublesome.
However, it is a critical method to manage networks.
Thanks for your input guys~

Happy Thanksgiving!
