IP address returns as domain name

[diablo24]

This is a general question regarding the return of an API call that returns a domain name instead of an IP address? Could this be a setting on the device? I'm experience this at a customer site and my code is expecting an IP address, instead is getting a domain name (www.yahoo.com). I'm still gathering debug logs, but I wanted to know if this was possible.

Thanks in advance,

Could you give us a hint as to which API call you are referring to?

Things like firewall rules can have both IP addresses and FQDN's.

Sorry for the delay in my response. I had to debug our customer log and find out which device it was coming from. The API in question is:

https://api.meraki.com/api/v0/networks/{networkId}/l3FirewallRules

I was just wondering if this was some setting on the device we can turn off? We have our application deployed for a few years now, and this the first time we've run into an issue like this. 

Thanks,

I found that starting in 13.4:

 In MX 13.4 and higher, fully qualified domain names can be configured in the Destination field.
