Subject why do I have to use internal IP for EC2 nodes?

says:

"

Note


In the - seeds list property, include the internal IP addresses of each
seed node."


why do I have to use internal IP?

on a EC2 node,

hostname resolution seems to directly give its internal IP:

$ host aws1devbic1.biqa.ctgrd.com
aws1devbic1.biqa.ctgrd.com is an alias for
ec2-50-17-3-229.compute-1.amazonaws.com.
ec2-50-17-3-229.compute-1.amazonaws.com has address 10.28.166.83

so using the public DNS or internal IP seems to be the same thing, or
something I'm missing ?

Thanks
Yang
