As go captures by reference the callbacks hold
pingerby reference and they will all wind up taking the source from the last pinger the loop processes.Assigning source to a local variable that ensures that each pinger's callbacks capture a reference to that variable which is unique to each pinger and hence that the correct source is reported.
