There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
It is just an example,sometimes,it is very useful,such as i can add score for below rDNS:
xxxx.dynamic.163data.com.cn
xx-xx-xx-xx.hostwindcloud.com
xxx.dailup.xxxx
These IP has default RDNS,but not customer's domain.
