 +NOTE: In current versions of aireplay-ng,​ the initialization vector number changes on each injected packet since a push-down stack of the most recently received packets is used.  The following sample file shows examples of unique injected IVs: [[http://​download.aircrack-ng.org/​wiki-files/​other/​arpinjection.new.cap|arpinjection.new.cap]]
