    Hi vishu_chavan,

    I have a couple of ideas that you might need to check. Are you using ZoneRunner (Local BIND) at all, or is all of your DNS traffic just going to Wide-IPs? Do you get positive results from the ISC genreport tool or the ISC EDNS compliance test website? https://ednscomp.isc.org/ 

    I'll assume you saw the relevant KB, but i'll paste it here: https://support.f5.com/csp/article/K07808381

    Unfortunately the 11.x branch is quite old, is there any possibility of upgrading to a later version?

    Thanks,
    Josh
