How to perform a dig command using iControl?

[fubarSUSHI]

Im trying to figure out any information on using dig commands or its closest equivalent using iControl?

Do you want to execute dig on the target BIG-IP remotely to (perhaps) test the DNS resolver on the box? If so, executing ping via POST /mgmt/tm/util/ping would do. Pinging to a remote device with its domain name would resolve its IP address. For example, ping'ing to www.google.com from my test BiG-IP;

curl -sku admin:admin https://<BIGIP>/mgmt/tm/util/ping \
  -X POST -H "Content-Type: application/json" \
 -d '{"command":"run", "utilCmdArgs": "-c 3 www.google.com"} ' | \
 jq -r .commandResult
 
PING www.google.com (172.217.14.228) 56(84) bytes of data.
64 bytes from 172.217.14.228 (172.217.14.228): icmp_seq=1 ttl=128 time=198 ms

P.S. Do not forget the "-c 3" ping command option. Otherwise, the ping runs forever, which results in REST call timeout. See man ping.

Ah, we do have /mgmt/tm/util/dig endpoint.

curl -sku admin:admin https://$HOST/mgmt/tm/util/dig \
  -X POST -H "Content-type: application/json" \
  -d '{"command":"run", "utilCmdArgs":"www.google.com"}'  | \
  jq -r .commandResult
