Throws:

                         throws IOException,
SQLException

Throws:

IOException

SQLException

getTopLevelDomains

public List<DomainName> getTopLevelDomains(DatabaseConnection conn)
                                    throws IOException,
SQLException

Gets the contents of the dns.TopLevelDomain table. Please note that these are only our manually configured entries, and do not contain the full list from TopLevelDomain.

Also, this is a list of effective top-level domains, for the purposes of domain allocation. This means it includes things like com.au, whereas the TopLevelDomain only includes au.

TODO: Automatically maintain this list from the TopLevelDomain source, with an "auto" flag. Add/remove as-needed when auto.

TODO: Have a flag "isRegistrable" that enables/disables a domain as being allowed for use by clients. Something marked isRegistrable and auto should never be removed? Instead of removing auto entries, have a "removed" timestamp showing when it no longer exists?

TODO: Allow a comment on each entry, too.

TODO: This could replace ForbiddenZones by adding more specific entries, and marking as isRegistrable=false?

Throws:

IOException

SQLException
