Dns question

[Sina Bahram]

Hi Laura,

*chuckling*

I don't suffer from being insane, I rather enjoy it.

That about explains my state of mind lately, ... Good to hear from you dear,
whatever list we're on.

Take care,
Sina

Hey Sina -- I like that little assertion -- "if I were anyone else, I'd tell
myself"...
Think of the ramifications...lol
Kind of makes you want to reassess yourself every day to be sure you're not
someone else...
Sorry, I don't have an answer to your questions, but the thread is
interesting.
Good luck, and if you find an answer i hope you'll post.

That's exactly my point.

Isn't that bizaare?

hospital.com has been owned since like 1997 by some company in California,
yet if you do a dns query ... You get nothing!

Now, I'm a computer science student, and I sincerely don't mind reading the
RFC's and the millions of other insanely boring documents detailing the DNS,
or excuse for DNS, protocol and structure we have on this planet; however, I
do have a problem with things not conforming to said standard.

Obviously, at this point, I am still looking for things that I am doing
wrong, not for things that they are doing wrong. I just can't find anywhere
else to look. My whoel program is 10 lines for goodness sakes ... A few more
if you count the braces, *smile*.

If I were anyone else, I'd tell myself.

*smile*, fustrated much?

But, *sigh*, this is quite agrivating, and I really really appreciate you
taking the time to lookup those sites.

Please let me know if you have any incites at all.

Take care,
Sina

I just tried `host` and `dig` to look up www.hospital.com and
www.patient.com, and I could not find any IP numbers for either URL.
I'm not sure what you mean by these URL's being 'owned', but they do not
hseem to have any associated IP numbers, hence the DNS look up failure.
HTH, and have a _great_ day!
