[Gnso-impl-thickwhois-rt] Contact validation rules review.

[gtheo]

Hi Guys,

Let's get technical ;)

Contact validation rules.

-Name, organization, address 1-3, city, state.

According to the rules , max length is 64, some Registries do indeed 
limit this to 64. however the EPP standard is 255.

I suggest Verisign sets this to 255, as it is very likely we will 
encounter addresses longer than 64. I have seen addresses in India that 
look like this: "#46, 1st floor, 4th Main road MLA layout, behind the 
stadium, take the stairs right next to the cafeteria".

I am not going to guess how things are organized in other parts of the 
world, again we are talking really old data and one can only suspect 
that Registrars been using the EPP standard.

-Email

My interpretation here is that there is no support for IDN TLD's as it 
must end with a 2-63 char string.

There is use for brackets regarding the domain name [].  Usually used to 
email an IP address.  The regex actually prohibits this, but if you want 
to support this then you support both brackets or no brackets, the 
current specification lists them as individual optional brackets.

In the user part, the following characters are supported ! # $ % & ' * + 
- / = ? ^ _ ` { | } ~
We actually do not support those as most registries do not support them 
and we ran into some issues when we did support them back in the day. 
That being said + is somewhat used, for example, Gmail to tag mail 
(user+tag at gmail.com).

So all in all nothing major that cannot be adjusted in time and some of 
it can be ignored if decided otherwise, some not, idn email support for 
example.

Best regards,
