Introduction:

Figure 1 illustrates the approach by example, where there
are twelve hostnames with ASNs embedded, most of which
match a training ASN we inferred using other methods.
Conceptually, we conclude the regex accurately represents
the naming convention for the suffix if the regex usually
extracts the training ASN from the hostname, and the regex
behaves this way for numerous routers with names in the suffix.

We are at that stage where we need feedback from operators
to validate/improve our algorithm. We include below a set of
inferred names for routers in several hundred domains.

If you would be willing to donate a few minutes of your time
to validate inferences (or let me know of errors) for any
domains you are intimately familiar with, please contact
