## Ex      : $> ./dhcp_ct dc1 ct 192.168.0.{1..254}  # <- Would register a new node in consul catalog using a free IP and HOSTNAME

## cUrl, used with "-K -", reads the config from the stdin, but waits for stdin's EOF before executing any HTTP requests 
## See : http://comments.gmane.org/gmane.comp.web.curl.general/15001

## Using the split's filter options allows starting and piping a stream to a new curl's stdin every N requests
## A same connexion can be kept alive for those N requests, making perfs much much better 

## TODO : Find a way to parallelise several curl in a "xargs -P" way

## Example : (the for loop is there to simulate some real stream, and to demonstrate the curl's required format)
