Installer promts to provide IP address only when IP cannot be resolved from hostname using DNS. So something happened to DNS after uninstall.

In case you have installed IPA DNS, you may experiencing this bug:
https://fedorahosted.org/freeipa/ticket/5262
or this
https://fedorahosted.org/freeipa/ticket/5875


However, I cannot reproduce this behavior on master (except #5875).

Can you check the values in /etc/resolv.conf after uninstall?

After the uninstall /etc/resolv.conf uses a DNS server that is not able to resolve the hostname/IP. I had an entry in /etc/hosts, but this was removed during the uninstall. If I add it again, the message I mentioned, doesn't appear any more. I hope, this helps you to reproduce the situation.

Do you want to configure integrated DNS (BIND)? [no]: yes

Enter the fully qualified domain name of the computer
on which you're setting up server software. Using the form
<hostname>.<domainname>
Example: master.example.com.


Server host name [autohv02.trustcli.test]: 

Warning: skipping DNS resolution of host autohv02.trustcli.test
The domain name has been determined based on the host name.

Please confirm the domain name [trustcli.test]: 

The kerberos protocol requires a Realm name to be defined.
This is typically the domain name converted to uppercase.

Please provide a realm name [TRUSTCLI.TEST]: 
Certain directory server operations require an administrative user.
This user is referred to as the Directory Manager and has full access
to the Directory for system management tasks and will be added to the
instance of directory server created for IPA.
The password must be at least 8 characters long.

Directory Manager password: 
Password (confirm): 

The IPA server requires an administrative user, named 'admin'.
This user is a regular system account used for IPA server administration.
