Hi. Is it so that many proxy routers and fire walls filer away ping signals? My computer is inside a company LAN and I can't get a ping answer from anything outside the LAN.
Thanks in advance, Gunnar

But it doesn't tell how many nodes it crosses. This is vital to check the network problems. Just pinging and getting IP is no way a productive. NeoTrace, a software is ideal tool to do this. If it's ping, they must know about tracert too. by the way, you can give them a tip like " ping -t " which will ping the ISP continously and keep the connective alive. It's useful when connection is slowing down or when server is irresponsive.
If ISP's DNS server is lousy, OpenDns.com is very good place to visit all the cached internet.

The reason using the raw IP address in the URL doesn't always work is that there may be more than one website hosted on a given IP. (This is called "virtual hosting".) The webserver software uses the domain name within the URL to determine which site to retrieve.
For example, although "ask-leo.com" resolves to "72.3.133.152", so does "www.pugetsoundsoftware.com". If you use the raw IP on the URL, the webserver has no way of knowing which site you want, and will use some default programmed into it.
As much as I've used ping for network diagnostics, it never occurred to me to use it for simply resolving a domain name. Thanks for the tip.
My tool of choice--habit, really--for resolving domain names is nslookup. It exists specifically to query DNS (Domain Name System) servers.
All of my systems come with nslookup already installed. (I run Windows XP Pro, Mac OS X, Linux, and FreeBSD; just got rid of my last Irix system, which had it, too.)

If ask-leo.com = 72.3.133.152, how come when I try http://72.3.133.152:80/who_is_leo.html, it doesn't work?
