Cannot access certain websites with IP addresses beginning with 192 1

[kensv]

I have a DSL modem connection to the internet and have been able to access all websites for a few years. Recently, however, I stopped being able to access certain websites, (hp.com, adobe.com, sportingnews.com) I thought it might be my internet security software run amuck, so I turned it off. Still no access to these sites. (When I try these sites they simply time out). I can access all other sites just fine, by the way. After reading some posts on this site, I tried pinging from the DOS prompt. I found that all the sites I cannot access begin with the IP address 192, (i.e. 192.x.x.x) I'm running Win98SE. Can anyone give me an idea how to fix this problem? Thanks.

This should do it.

Connect to the internet.
Run winipcfg.exe (in start -> run)
Your IP is more than likely says 192.168.0.x with your mask set @ 255.0.0.0
Make sure the mask is 255.255.255.0.

WheeDoggy,
You are correct, my IP is 192.168.0.x with mask set @ 255.0.0.0, however I cannot change the mask. My computer gets it's dynamic IP address from the ISP server. I did try and change to static IP address to set the mask but when I reboot it still got the IP address/mask from the ISP server and the mask was still 255.0.0.0
Also, I'm curious why it has been working fine for a couple of years and then recently it quit letting me access these sites. I'm thinking something got corrupted, do you have any clues where I could begin along that train of thought?
Thanks,
Ken

Goto Start-> Run

Type winipcfg [enter]

Hit Release_All

[OK]

Reboot

After reboot, try to connect to hp.com again.

Let me know what happens -

Looks like whoever is providing you your IP address has made a change.

because your subnet mask is 255.0.0.0, everytime you attempt to go to a 192.x.x.x site, your computer assumes it is on the same lan as you, and it never sends it out to the internet.

I would call the ISP and complain!

WheeDoggy,
I did what you said, ... and it worked! Thank you very much.
So I was just being assigned a bogus subnet mask when I got my dynamic address from my ISP, is that what was happening? And then by releasing all and then rebooting I'm forcing the assignment of a new IP address and subnet mask?

And by the way inikis, I did call my ISP for tech support a few months back and they left me with: it was my problem. Never had me check subnet mask or anything close to that.

I guess I need to call back and complain that I'm getting a bogus subnet mask at times. My real question is, is there a way to prevent this from happening again?

Thanks again to both of you for your input.
Ken

Hi Ken -
&quot;My real question is, is there a way to prevent this from happening again&quot;

Your IP & Subnetting are provided by your ISP - that's the point of dynamic IPs. Their problem, basically.
You could always try release/renew if you come across the problem again.

That's assuming your ISP IS actuslly giving you a bogus subnet mask; that it's not an issue on your machine. I find it hard to imagine an ISP making such a basic subnetting mistake as this! (Having said that, I work for a large(ish) ISP - some of the things they do from time to time )
