Ah, but "why is it done" and "does it cause any harm" are two different questions. I can't think of a good reason as to why. Perhaps it is something related to how the IETF is a non-profit org and there is a perceived requirement to make sure its resources are not being overly abused.

I don't see the harm in doing so. It isn't the raw access logs, so one can't see what was accessed. It isn't useful as an attack vector because there is a mixture of servers/crawlers and desktop IPs there; one might just as well attack the entire address space. > > > Peter > > On May 20, 2011, at 10:35 AM, Keith Jenkins wrote: >> >> Just out of curiosity, does anyone on this list have any opinions >> about whether website owners should publicly post lists of their >> visitors' IP addresses (or hostnames) and to also allow such lists to >> be indexable by search engines? >> >> For example: >> https://www3.ietf.org/usagedata/site_201104.html >> >> Keith -- Peter Murray [log in to unmask] tel:+1-678-235-2955 Ass't Director, Technology Services Development http://dltj.org/about/ Lyrasis -- Great Libraries.
