The first test I’ve undertaken is to test two name forms in an ad campaign over the past few days: heres an example of the test: xm--u82aa292f-c13-s1518066940-i00000000 _xm_-u82aa292f-c13-s1518066940-i00000000 test 1: the label starts with the characters: x m - - test 2: the label starts with an underscore and contain an underscore within the label results Test 1: tested across 15,168,394 presented ads. 96.9% of end systems resolved the name and fetched the web object, 3.1% failed to fetch the web object Test 2: 39.7% of end systems resolved the name and fetched the web object. 60.3% failed to fetch the web object There is always a ‘drop out’ of users who do not fetch the web object, and 3% falls within the experiments error bounds. xm—<whatever> appears to be a label that generally works when presented to browsers as part of a scripted URL to fetch. _<whatever> appears to trigger some response from many systems that preclude its use in URLs presented to browsers to fetch thanks, Geoff _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
