How to check if a string parameter can be an IPv4 or an IPv6 or nothing in an iRule ?
How to deal with that question in the best optimized way to code it versus cycles ? "How to check if a string parameter can be an IPv4 or an IPv6 or nothing in an iRule ?" I have already looked at "IP::addr .... mask ...scan ..." without any simple efficient way. Some helps ? Some few lines ? or TCL function or undocumentated iRule command ? Many thanks :-)
Is it cmpulsory to enable DNS IPv6 to IPv4 to host IPv6 listner?
Comment made 1 day ago by Mihir Joshi 2 Hi, I have a question. Is it compulsory to enable option "DNS IPv6 to IPv4" if we host IPv6 listener on BIG-IP DNS (GTM)? We are experiencing strange issue. User belong to one of the Europe region not able to connect application when they connect from their home Wi-Fi which have IPv6 addresses enabled. On GTM we have IPv6 listener and IPv4 listener which shares same DNS profile which enabled with option "DNS IPv6 to IPv4" (Secondary). Because of this end user receives two records in IPv6 addresses in format of "::xxx.xxx.xxx.xxx". Do you think this could be a reason for issue we are currently experiencing? When we ask client to change their IP schema from IPv6 to IPv4 it works perfectly fine. Regards, Mihir
