CNAME Flattening
Hi, F5 GTM's are our domain (let us say example.com) authorized DNS servers. Our website is accessible on example.com and www.example.com. We are migrating to the cloud and the DNS queries will still hit the GTM's and we need to redirect to the Cloud front door (CNAME Record). The existing set up is with the 2 WIP's(www.example.com and example.com) on the GTM points to the pool. To migrate, we have created the CNAME records in the zonerunner , the challenge is we cant create the CNAME record for the root zone (example.com) as there will be NS records etc. We have created CNAME based WIDEIP for example.com with the CNAM based pool (Cloud front door). When i access example.com , we get the error on the browser saying "DNS prod finished nxdomain error". When i dig specifically with CNAME on google DNS, Dig interface I can see the CNAME record. Tried with few irules, however we are getting errors. ######################################################### when DNS_REQUEST { set queried_name [DNS::question name] set Cloud_FD "abc.xyz" if { [string tolower $queried_domain] eq "example.com" } { set cname_record "${queried_name}. 300 IN CNAME ${Cloud_FD}." set new_rr [DNS:rr ${cname_record}] DNS::answer clear DNS::answer insert $new_rr DNS::return } } ##########################################################
F5 DNS for External websites
Greetings everyone, I require assistance with F5 DNS resolution for external websites. I have a website hosted on GoDaddy, for example, mapmap.org. Currently, it points to a single A record, and I aim to implement load balancing between the IPs. To achieve this, I configured a wideip named mapmap.xxx.org and created aliases for mapmap.org and www.mapmap.org. also, pointed Godaddy DNS to my F5 DNS listener IP /NS by removing A record in Godaddy dns. Subsequently, Zonerunner was set up with SOA and NS, using the F5 Listener IP. Upon performing an nslookup, I successfully obtained the answers. However, I noticed a .org. zone created as self, with these alias records falling under that zone. Is it acceptable to have a zone with .org and include these alias records, or is there an alternative approach for this configuration? I appreciate any assistance provided.
