Anyone?
FWIW, I took a look at my scans data and there's a lot of this around. Of the 5477 PTRs with spaces, in approximately ~490 domains*, those with more than twenty hosts with PTRs containing spaces are the following: 2178 bbox.fr (still) 961 misc (basically, domains that don't exist, garbage rdns, etc.) 255 yorku.ca 203 hostforweb.com 157 teknotel.com 156 uncg.edu 129 lacoe.edu 55 is.co.mz 52 uni-bonn.de 41 ncsu.edu 41 bell.ca** 40 fuse.net 36 dartmouth.edu 27 gatech.edu 26 uni-goettingen.de 25 isu.edu 25 csub.edu 21 qut.edu.au Anyone from these orgs that cares can contact me offlist for more info, or as someone who saw the bbox.fr post did, forward to the relevant people and ask them to do the same. FWIW, some involve leading, some involve trailing, but most contain spaces in the labels themselves. * FSVO "domain" ** I had a contact at bell.ca but she has since retired and they have apparently kept introducing more bad rDNS.
