Addresses are always FQDN-v4 or v6, for example office-pfx-v4
The addresses are then added to an address-set:
address-set office-pfx {
address office-pfx-v4;
address office-pfx-v6;
That address-set can then be added to a larger address-set that should have a function name, for example offices
Sunet specific addresses always start with SUNET-, for example SUNET-infra-cpe-mgmt-links
