Router Naming Convention for bit.nl, 201708

Regular Expressions:

^[^-]+-\d+-[^\.]+\.([a-z]+1\.[^\.]+\.network)\.bit\.nl$
^[^\.]+\.([^\.]+\.[^\.]+)\..+\.bit\.nl$

Statistics:

Training routers with at least two clustered interfaces: 8
Positive Predictive Value: 1.000
True Positives (green): 18
False Positives (red): 0
IP literals extracted (red): 0
False Negatives, identifier extracted (orange): 1
False Negatives, not matched: 3
Training routers with a single interface in suffix: 4

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
	o	No regex matched the interface, but the interface was the only interface in this suffix on the router
	*	A filter regex matched the interface
