1) What might happen on the off chance that one endeavors to send a measure of coins to an IP address that isn't running the program?
2) What might happen on the off chance that one endeavors to send a measure of coins to an invalid Bitcoin Address?
3) What might happen on the off chance that one endeavors to send a measure of coins to a Bitcoin Address that no one claims?
I thank answerers for extending my insight.
1. I don't really understand this question, but you don't need to run program (wallet/nodes in this case) to receive your coins since the transaction is recorded on blockchain and can be accessed by anyone anytime.
2. If you mean by address without right format/standard, it's impossible since it violates the protocol and nodes/miners would reject it. But most bitcoin wallet have address validation (by check total character, few first character, etc.) to prevent that, so you don't need to worry about small typo.
3. The coin would be lost forever assuming the receiving address have valid format.
P.S. if you want to extend your insight, then move this thread to
Development & Technical Discussion where you can get better/detailed answer.
