If this is in your router than it is being blocked - unless you don't have a router, in which case I suggest you run a firewall (or enable the Windows Vista firewall which should be on by default).

You could contact TelstraClear and ask them to contact the customer to advise of this problem...

There were a number of worms circulating via exploits in XP a couple of years ago. It seems they're still not dead. How did you get these records? Do you have an existing firewall? If so, you should be fine. If not, just download Zonealarm or something to that extent. As Mauricio says, send TC an email outlining the IP's in question (with time stamp). They'll send the customers a warning. Most likely they don't even know about it.

Thanx for the replies

Yes I do have a firewall. I used Outpost but it slows my browser down ( Firefox) too much so I use the firewall that comes with Kasperksy which blocks fine.
I know I am blocking these exploits atm but heres the thing. I changed from XTRA adsl to Telstra cable a couple of weeks ago and immediately was inundated with viruses and Malware which took ages to remove without a HD  format etc. It seems having a new IP everytime I boot up with Adsl may thwart attacks and now I'm a sitting duck.
Perhaps  asking for a diff IP would help? I know I am blocking them but I wasn't being attacked before I changed to cable. What do you guys think?

I just sent an email to the admins at Telstra:

list.admin@team.telstraclear.co.nz

Dear sir/s,

I am coming under attack from the following Telstra IP's

Please advise what I should ( or you) should so. I noticed when I changed from Xtra adsl to Telstra cable a couple of weeks ago I received a lot of malware and viruses I didnt have previously.

I am a security engineer -  that is just netbios traffic, windows networking, its not malicious, For example if you plug your PC straight into the cable modem that will appear as just a nomral networking interface, windows sends out netbios traffic. You will be seing port 135, 445, maybe a bit of 139.

It's just noise.
infact nothing there would raise any alarms except the worm traffic. which is outside of the Telstra Range anyway.

Uh, I thought RPC was TCP 135 and TCP 137-139 were typical netbios over tcp/ip. Mind you I'm only a rocket surgeon :(

tend to just shroud it under the one term. It will be windows sending out its networking crap. :D
