You can persistently set a property to an IP address through the ATG Control Center Components window only if one of the following conditions is true:
No DNS entry is available for that IP address on your network.
A DNS entry is available for that IP address everywhere on your network.
Java tries to convert a numeric InetAddress to a host name, and if it succeeds, the host name alone is employed when Java saves or transmits the value of the address. Only when no host name is available is the numeric form used.
If you need to set a property to an IP address, either set the DNS entry as described above, or set the property by editing the properties file, rather than by using the ATG Control Center.
