127 is localhost. IOW, your computer. Normally 127.0.0.1

A TCP/IP primer. Not an entertaining read but you might find it useful to
learn a bit about TCP/IP addressing.

Thank you all.

Why would my system need the 127.0.0.1 for "loopback"?

I believe I have heard it described as "the computer sometimes has a need to
talk to itself".

I always, myself, compete with others to be the stupidest ...

;:-D

So, I knew that 127.0.0.1 is the  localhost, that is myself.

It's Ok.

Now what's the difference between 127.0.0.0 and 127.0.0.1 or whatever form
127.0.0.0 up to 127.225.255.255 ?

Darn.  You want an answer to your question.  That's part of a netblock.  But
I don't think it answers your question.

Servers use the loopback address more than pc users do.  For example, if 
you are using mysql and a process (say php) needs to connect to the 
mysql database it does so by connecting to localhost:3306 or 127.0.0.1:3306.

Interresting.

Do you yell before or after you push the power button (at start-up I mean,
because, at shut-down it's is a relief but of no use) ?

What's the most reliable ?

Dear James, 
 I see no reason for you to apologize in advance for the question you 
asked.  
 Perhaps the regulars here ought to do a gut check.  Are they hanging out 
here to help people, or are they tying to prove that they know more than 
anybody else?

At start-up, I am very still and quiet because I do not want windows
to be disturbed while booting up and I pray that my data is still
intact. It is a shutdown when I have to use the power button due to  a
freeze that causes me to exhale a windstorm of profanity that would
make a sailor proud.

Sending proxy ID type 4 0.0.0.0/0.0.0.0 --How can I populate these BM3.8
I have narrowed a previous issue to this problem. My IPsec compliant firewall (PIX) expects these to have values (I'm assuming that they should contain the IP and subnets of the BM38 server and the other firewall) populated. The IKE screen on the BM3.8 server reports "Sending proxy ID type 4 0.0.0.0/0.0.0.0". The PIX reports "testpix(config)# IPSEC(validate_proposal_request): proposal part #1, (key eng. msg.) dest= 192.168.1.1, src= 192.168.1.2, dest_proxy= 0.0.0.0/0.0.0.0/0/0 (type=4), src_proxy= 0.0.0.0/0.0.0.0/0/0 (type=4), protocol= ESP, t...

Hosts file and 127.0.0.0 ?
I altered my Windows "hosts" file to point all those stinking web page ads (eg, ads.x10.com) to my local host 127.0.0.0 Works great and makes reading web pages much easier. The pages have lots of red X's on them, but I prefer that over the ads. I read somewhere a while back that there was a way to point these ad URL's to a "1 x 1 transparent pixel" instead of 127.0.01 so even the red X's wouldn't show up on the page (they would be replaced by this clear pixel). My question is, what do I replace the "127.0.0.0" reference with to make ad ...
