[db-wg] country attribute: "ZZ" for unspecified?

Dear DB-WG,

might there be a consent for introducing "ZZ" as an allowed value for 
the "country"-attribute for "unspecified"?

Reasoning:

- ISO 3166-1 [1] specifies "ZZ" as "User-assigned code elements are 
codes at the disposal of users who need to add further names of 
countries, territories, or other geographical entities to their in-house 
application of ISO 3166-1, and the ISO 3166/MA will never use these 
codes in the updating process of the standard.".

- Many current entries do not specify the correct/meaningful value for 
country. Examples includes:
    [2a] RIPE-NCC-K-ROOT: NL
    [2b] TELTEK-1: GB, but: country is really Europe and Middle East
    [2c] ORG-AFNC1-RIPE: EU, but: country is really somewhere in African 
Region
    [2d] IANA-BBLK-RESERVED1: EU, but RFC1918 network
    [2e] EU-ZZ-163: EU, but: Country is really world wide
    [2f] LUXLINK-003: DE, but: These IP's are really World-Wide

- For automated statistics it would be nice to have a special 
designation for IPs which do not correspond to a specific location, so 
that they are easy to filter.

- It could be used for (global) anycast services, too.

- ARIN & AfriNIC legacy entries could get a "correct" country.

- Documentation says: "There are no rules defined for this attribute.", 
but the attribute is mandatory? Shouldn't we change that? Either make 
the attribute optional or specify, what it is supposed to contain.

- I am dreaming: Wouldn't it be 
<http://dict.leo.org/ende?lp=ende&p=5tY9AA&search=desirable>desirable to 
have a designation for "world", too?

- We already have a least on strange countries "EU", which does not seem 
to be part of ISO 3166-1...

I'd like to hear your opinion...

Best regards,

    Christian
