Router problems

[eddds40]

Been working on a diagnostic machine for cars. Sent out from one of the major car mfg. It was supposed to be setup dhcp enabled which I did , in a existing LAN , where had ISP service with regular pc that could connect to the car mfg. Still wouldn’t connect to the car mfg. site. Spent much time on help line, where I learned nothing. OK talked to some tech’s that work on hospitable machines a lot and they tell me they been having a lot of same problems , as far as they are concerned it is in the switching. This is a observation that I made would like some comments on.
When router assigns ip address it is in this format xxx.00x.0xx.0xx OK so address is full by using zeros where their isn’t any number for example 192.168.1.1 would have 192.168.001.001 OK using the ping command I can ping 192.168.1.1 but not 192.168.001.001 WHY? The original router was a zonett zsr0104cp, I tried replacing with a ovis link didn’t work. Replaced with a zsr0104b which solved all the problems with the machine connecting to internet there the local LAN to WAN. I know original router was good for connecting to www but wouldn’t work on the new diagnostic machine. I am unable to access the os in the machine so not much help from looking at that end.
Anybody got any insight into this problem esp. with the use of zeros in ip addresses.

Leading zeroes in devices aren't all that uncommon -- most of the printers and copiers at work display things like 010.001.003.006. They're still using what we refer to everywhere else as 10.1.3.6 though -- the IP address is just four normal decimal numbers.

However, using leading zeroes in IP addresses in Windows makes it treat the numbers as octal (base 8), so you aren't pinging the machine you think you are. Pinging "192.168.001.023" in Windows, for example, is actually the same as pinging "192.168.1.19".

Moral of the story: Ignore the leading zeroes that the device displays, but make sure you don't include them when you use Windows. If the device is showing xxx.00x.0xx.0xx on its screen, ping xxx.x.xx.xx from Windows.

Thanks for the reply here is another insight I got from a friend
Also, pinging 192.168.001.001 or 192.168.1.1 will be different depending
on which command shell you use. In Windows 98, ...001.001 will not
work. In Windows XP it does.
I was on a win 2000 machine so that shouldnt of mattered. Did get it working with different router so must of been firmmware in router or the diagonistic machine.
