The FTSC documented one:
- if there's an address in the IBN flag use that one and only that one
- if the IBN flag doesn't include an address take all the addresses from all 
INA flags

The undocumented standard:
- take all addresses in IBN and INA flags

Q: How ports are handled by the undocumented standard? If we have 
INA:my-bbs.ddns.org and IBN:my-bbs.dyndns.com:8080 for example, does the port 
number also apply the the address in the INA flag?

Over here most of the distribution nodes have several FQDNs for resilience. If 
one dyn-DNS service fails the node is still reachable via its second FQDN.

ciao,
