Hey,

 

In case of EDNS tester had scored my domains as "Minor problems detected!" and in my need to postpone my BIG-IP update to 11.6.3.4 due to possible new issues not yet tested, do you think is good workaround to apply the code from here: https://devcentral.f5.com/s/articles/implementing-client-subnet-dns-requests, plus adding code to fix buffer size "DNS::edns0 sz 512", it covers all is needed for awhile? This way, should I be "compliant"? Is it a good workaround till the BIG-IP version can be updated or need I just to plan upgrade soon I can?

 

Thank you in advance.
