IP Address Mystery

I am running a wireless broadband Alltel K650 in a KR1 wireless router,
properly secured with passwords, etc.

I am set up for dynamic DNS. For the past several days, I have noticed
that my IP address will remain the same even when I turn the router off
and move from my home office to my office, which takes 45 minutes or so
from shutdown to start-up.

This is not the way a laptop wireless set for dynamic DNS should work.

What gives? Has Alltel decided to assign address to individual users or
am I locked to an address so it makes it easier for some hacker to keep
up with me?

I should have a new address every time I break my Alltel connection and
reconnect.

What gives?

Dynamic DNS just means you MIGHT get your IP changed. This isn't done to
prevent "hacking", a terrorist term used to make firewall and antivirus
companies rich. It's done to prevent users from becoming SERVERS and
using upload bandwidth. They only time it is changed is when "they"
decide you are a bad boy and need to be put on a rotation to prevent you
from running your server. Other times, they leave your phone number of
the modem tied to it to keep the load on the DNS servers down, which
makes them run faster for all.

I've had the same IP for years on dynamic DNS cable. It didn't even
change when I swapped DOCSIS modems.

Everyone you connect to must have your IP to send data back to you. It
has nothing to do with "hackers" who have no more chance of "getting at
you" one way or the other. The bad boys operate by installing servers on
your laptop usually sent in a malicious email you opened with a Swiss
Cheeze email client like Outlook or Outlook Express. If you have no
malware installed, it doesn't matter if anyone calls all 65,535 ports of
your machine. Your system simply reports the port listening, if some
stupid Windows program, or Windows itself, has forgotten to close
it....or it reports the port closed, go away.....or, if you have a
firewall like you should have, it doesn't answer any calls from any IP it
hasn't called, making you appear invisible.

Now, EVERY OS, all of them, have had some problems with being attacked by
thousands of calls per second or have handled malformed packets sent to
them in an unexpected manner due to screwups by the OS coders. So, M$
and the other OS coders are always sending out disguised "upgrades" or
"improvements" to cover these tracks as fast as they can. Here's some
organizations who do NOT sell scare tactics, but are involved in making
the net safe:

Microsoft is the biggest target because it has always been the biggest
asshole in the computer biz. Any Microsoft product, not just Windows, is
always targeted and has the most known vulnerabilities because of the way
the corporation acts to its users. Open source software, like Linux, is
just as vulnerable as Microsoft, but, because of its open source hacker
roots is simply attacked much less to find them. Mac OSX isn't
invulnerable, either. None of them are.

The number one protection product is Symantec that will ALWAYS have its
"haters" because they charge money for their services. However, to have
a staff of hackers to find and fix what the bad boys are doing, you need
to PAY them. I'm paying on all my computers except my Linux tablet. If
it got trashed, I'd simply reflash its Linux OS and load it back up,
which is just so easy. The hackers are so busy writing great software
for it, they have no time to attack it...(c;

I've recently purchased the Norton 360 3-computer deal, dropping my other
Norton subscriptions for NAV and Internet Security I've used for years.
One license fee for 3 computers, instead of 3 separate licenses.

Here's what I'm paying for:

Here's a new worm discovered Apr 30th I won't get:

043015-2430-99&tabid=1

The new 360 does a lot more for the browser than the previous products.
Browsers are much more of a target, now, than your email. Just browsing
websites is all it needs. 360 goes crazy when it bumps into one it
doesn't like...(c;

That certainly has not been my experience.

I keep a log in longhand of every IP address immediately after logging on to the
Alltel system. Unfortunately, I do not date them.

Here on my den desk, I have one sheet before me with 44 different IP
addresses. I would guess that this log is 3 weeks or so old.

I have another log in my office which will have close to the same number
of entries.

When I was having trouble with dropped connections, I would get 3, 4 or
maybe 20 different IP's a day. NEVER EVER the same one.

Some security systems will bar you if you try to log on to them with
several different IP's within a set length of time. Theory being that
two computers are trying to use the same ident and password.

So this one IP for three or four days even after a log off of 45 minutes
or so, is definitely a new thing with Alltel wireless.

Certainly in my area.
