True Positives (green): 7
False Positives (red): 1
IP literals extracted (red): 0
False Negatives, identifier extracted (orange): 0
False Negatives, not matched: 7
Training routers with a single interface in suffix: 5

Legend:

Green	+	Inferred identifier, true positive when evaluated against training data
Orange	-	Inferred identifier, false negative when evaluated against training data
Red	!	Inferred identifier, false positive when evaluated against training data
Red	x	Inferred identifier, but contains part of IP address literal embedded in hostname
	~	False negative, not matched
