config-network-object-group not accepting a hostname

[keithsauer507]

I am trying to add a hostname to a network object-group .

First I go into the object-group that I want to modify.  I then tried network-object host intellicare.tegile.com  for example, but I get an error on the host name, ERROR:  % Invalid Hostname.

If I do network-object host ? it shows Hostname or A.B.C.D Enter a host IP address or name.

Well I need to use a name here because the vendor on the other end uses a load balancer so the IP could change anytime.

How can I accomplish this?

you have to configure the FQDN in a network-object and reference that object in the object-group:

object network CISCO
 fqdn www.cisco.com
!
object-group network ALL-CISCO
 network-object object CISCO

Your ASA  needs to be able to resolve that FQDN to an IP address through DNS.
