// precondition : address is in list
// postcondition : the count of node with address has been incremented
{

        node* currPtr = list;
	int TotalCount = 0;

	do

		TotalCount++;
		currPtr = currPtr->link;
	}while (currPtr != list);

	return TotalCount;

Code:

void IPlist::updateCount(string address)
// precondition : address is in list
// postcondition : the count of node with address has been incremented
{
    int count = 0;
    node *tmp = list;
    while(tmp != NULL && tmp->IPaddress == address)
