Unknown IP addresses in my firewall logs (outgoing initiated web traffic)

Hi All,

This is a follow up on an issue I posted on a while back:

http://groups.google.co.nz/group/nz....3ee16bd7e417bc

I still don't fully understand, so I am looking for a little more
education albeit from a stronger base of knowledge now hopefully!

I have (again) an unknown IP address being accessed from inside our
LAN serving up a significant amount of data.

This time, the IP is:

210.55.204.214

If I do a search on that IP in Domain Dossier
(http://centralops.net/co/DomainDossier.aspx) I get the following
extract:

HTTP/1.0 400 Bad Request
Server: AkamaiGHost
Mime-Version: 1.0
Content-Type: text/html
Content-Length: 187
Expires: Thu, 06 Apr 2006 21:46:18 GMT
Date: Thu, 06 Apr 2006 21:46:18 GMT
Connection: close

Specifically, we see that 'AkamaiGHost' server again.

From what I was told last time, this *could* be a server used by
Microsoft to distribute updates etc.

However, my ISA 2004 server also shows traffic to the following
servers
in the same log:

download.microsoft.com
office.microsoft.com
www.download.windowsupdate.com
update.microsoft.com
au.download.windowsupdate.com

Therefore, I am now having concers that the IP address above is *not*
a windows / office update site of some sort since they appear in my
logs with their canonical names, not just an IP address.


Am I being too paranoid here? If not, and I block access to the IP
address totally, could that have a negative impact on our machines in
terms of failing to get windows updates (or worse, not even being
aware that there are updates available that they cannot get)?

Could it be some other form of updates (Symantec virus definitions for
example)? If so, how can I tell for sure?

I don't want to to block access to the site and find that it has
silently stuffed up something important that I don't find out about
for a few weeks.

Thanks,

Alan.

It will be valid for AT LEAST one month from the date of this post.

If you are trying to contact me after that time,
it MAY still be valid, but may also have been
deactivated due to spam. If so, and you want

Yup - but what does that mean in the context of my query as to actions
to take or not?

Thanks,

Hi EMB,

I did that already, but I cannot see how I can tell what is being
mirrored from a given IP at a given point in time.

Nothing I could find helps in terms of the decision I need to make, it
all just appears to be about Akami and what they do which is very
interesting but irrelavent to the question at hand.

Are you able to shed any light on the actual problem of whether to
block a given IP and what the implications might be?

Thanks,

Alan.

LOL

For what could it be *important* that you don't already know about?

All manner of large software vendors use the Akamai servers for
distribution of updates. I'm unsure as to whether blocking this
particular IP address would break that process or merely cause the
Akamai process to re-route your downloads to another server. Either way
the result won't solve your problems.

As you were told when you asked before, Akamai is a caching service used
by Microsoft among others. It is NOT a Microsoft distribution server. It
is a caching service. It is almost certainly benign. In the very very
early days these server were used as anonymous relays, but those days
are LOOONG past.

It is a caching service, subscribed to by a number of big content
suppliers, not just Microsoft. The NZ Akamai servers are hosted by Xtra
I believe.

Yes you are being paranoid.

Cheers,

Cliff

That's the nature of a cache. You don't know what's in it, but you know
that it has been accessed frequently in the recent past. You just know
that if you need to access something that happens to be cached, you will
get it quickly and locally instead of having to drag it in from offshore.

Cheers,

Cliff

Interesting point: For pages that originate overseas but are cached locally,
do ISPs charge their overseas bandwidth rate instead of their local rate? I
suspect many charge the overseas rate, pay Akamai's fee and pocket the rest.
