We always tell the client which IP's we are coming from. Mainly because we *don't* want to get
our IP's blocked by an IPS or by an unwitting admin. If you do not trust the admins will allow
the test to go smoothly, you should probably contact their managers to see that your information
does not get distorted.
Or you can simply ask them whether or not they'd like to be given that information. Occasionally,
we are told by the managers to not tell the admins to see if they notice the attacks. Doing the tests
from multiple machines has its advantages, especially when given a class C or larger to split up the time.
In our company tests are usually split up with internal/external/pbx & modems ect. But occasionally
we all work on a project together. Logs are definitly important, one thing I wish automated scanners
did would log what plugin/exploit caused the fault/issue. If the issue was caused during a penetration
test you should contact the company immediately and explain what exactly you were testing at the time
and work with them in identifying what the exact nature of the problem was.
Hope this helps,
