Check to see if you have a DNS server configured
hannesr@(lb01)(cfg-sync Changes Pending)(Active)(/Common)(tmos) list sys db dns.nameservers
sys db dns.nameservers {
value "10.199.22.2 10.199.22.6"
}

Nacreous1) If you don't have a DNS server configured - configure one.
2) If you don't receive any response to dig command - make sure you have UDP/53 connectivity to the DNS server.
3) If both commands succeed, assume that DNS on F5 is OK and you must update the DNS server's configuration to include a new A entry for your service name.
When done, retry your cURL command. Good luck!
