As you could have seen, Funceble have a column which is called SOURCE. Here, we document that column !

Funceble can return at the time we write this, 4 sources which are IANA,NSLOOKUP,SPECIAL and WHOIS. For two of them, it's easy to understand but for others, it's kinda obscure so let's start !

IANA

Short definition

IANA is the abbreviation of Internet Assigned Numbers Authority which is a ICANN department in charge for the allocation of globally unique names over the internet. In other word, his work is to make sure that there is unique domain names around the Internet.

Usage under Funceble

In Funceble we have a file called iana-domains-db which is a dump of the IANA Root Zone Database. We consider it as the official list of valid domains extension.

When do we get IANA ?

Well as mentioned previously, if the source is IANA its basically means that the given domain name(s) is or are invalid. So along with that source you will get an INVALID status.

NSLOOKUP

Short definition

nslookup is a tool for querying the Domain Name System (DNS) in order to obtain domain name or IP address mapping.

Usage under Funceble

In Funceble as described in the Status page, we use nslookup to check if a domain name or an IP is ACTIVE or not.

When do we get NSLOOKUP ?

As described previously, if the domain is INACTIVE and that result comes from nslookup, you get NSLOOKUP into the SOURCE column.

SPECIAL

Short definition

SPECIAL give us the ability to manage special cases such as domain who only have subdomains just like blogspot or other website.

When do we get SPECIAL ?

Here's the list of domain that are passed to SPECIAL :

  • *.blogspot.*

    • All 404 are returned as INACTIVE
    • All 302 which are blocked by Google are returned as INACTIVE

  • *.canalblog.com
