It can depend on the legal situation which is attempting to be complied with.
(1) For someone who needs immediate service, a search can be made of post office forwarding files - real estate and/or tax records - DMV license/registration files - the IRS for addresses to which tax refunds are mailed - etc.
(2) If you are simply satisfying a requirement for searching for an unknown person to deliver them notification of some pending legal action, usually the publication of the legal notice in a 'newspaper of general circulation' in the area, for a certain number of days, will satisfy the requirement. Contact your local Court Clerk's office to determine the requirement for your particular jurisdiction.
One can't ... one needs to serve the summons to appear to where someone lives ... no address available, nobody can serve the summons ... However, there are ways to obtain addresses for most anybody these days on the internet - may cost a bunch of $$, but it is possible.

Can I serve a summons to the defendants attorney if the defendant cannot be found

Yes it is.
conflict of interest
summons or subpoena, yes
No, the case can not continue until you have been legally served. When it is returned as unserved, the case effectively ends unless they issue an alias summons (i.e. additional attempt to serve you). What this also means is that the summons was returned to the court, and was not successfully served, therefore no process server has a copy to potentially serve you later UNLESS an alias summons is issued to try a second time to serve you. It is wise to keep watch to make sure this does not occur.
yes because the law states that every aralegalsummons serves apurpose
That depends upon the laws of the state in which the judgment was issued, the least amount of time would be 10 business days from the time the summons was served.
A creditor must serve a "summons", along with a complaint, not a "subpoena". A summons is a court's formal manner of acquiring personal jurisdiction over you and giving you notice of the claim made against you. A subpoena is an order for a witness to appear in court or at a deposition to give testimony.
