I am doing a survey to see what naming conventions are used for routers and router interfaces as part of a measurement study that I am conducting as a student at the University of Wisconsin Madison. If you are interested in participating please fill out my form at: https://docs.google.com/spreadsheet/viewform?formkey=dE1OYmVGcjlxV1YtZjB1QmJ... I am aware that this issue has been discussed extensively on nanog (and other lists). The purpose of this survey is to see in a structured manner which networks use which conventions, and get an idea for how automated the process of PTR record generation is across different providers. I am happy to provide high level results from the survey to anyone that is interested. Thanks for any feedback! -Joe http://www.cs.wisc.edu/~jpchaba
