Re: looking for operator validation for regexes that extract ASNs

❦ 11 mai 2020 20:03 +12, Matthew Luckie:

To support Internet topology analysis efforts, we have been working on an algorithm to detect AS numbers inside hostnames (PTR records) for router interfaces, and automatically build regular expressions (regexes) to extract them.

Hello Matthew, This work is quite interesting. I see you have also a page to build regex from router names for each operator. Did you already work on extracting city names/US states? This would be quite helpful as well. -- Take care to branch the right way on equality. - The Elements of Programming Style (Kernighan & Plauger)
