In that second answer the only not-aws IPv4 address that replies is: 198.180.140.2 -chris (yes this is the 'additional section' content from dig NS @<thing> domain) _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/[email protected]/message/JFVO7ZDLJVNVRX473S6ZR23HYZAJ3I4V/
