    As part of maintaining my list of Manitoban ASNs and their IPv6 status, I need to determine new Canadian, and specifically, Manitoban ASNs issued by ARIN. I had been doing this manually by reading through bgp.he.net/country/CA, but this was very time …

  • IP Quail API

    Sunday, September 14, 2014 in Programming

    Sunday, May 04, 2014 in Programming

    Thursday, April 10, 2014 in Programming

    Another huge blunder this week in the ubiquitous OpenSSL library secadv. This one’s called Heartbleed. You can easily check if your services are vulnerable at filippo.io/Heartbleed. This one is particularly scary as it allows reading random …

  • Learning Python: Part 2

    Sunday, April 06, 2014 in Programming

    I’ve moved up in time/history to the 1980’s with Python – INI files! I’ve modified one of my python scripts to now use ConfigParser to read in a .cfg file. The simplicity, built in functionality to do tons, easy …
