I think that is their block for globally recognised address other than that
it is not globally recongisable.

>From the ARIN, there is a statement shown below :
*The minimum block of IP address space assigned by ARIN is a /20. Smaller
blocks obtained directly from ARIN are the least likely to be globally
routable.
What does that mean ? Thanks.

You can find a lot of information about RADB on the RADB.net web
site. The
problem is that I never found some examples or explanations on how
large
ISPs use the information stored on the IRRd servers on real life.
Maybe
somebody with more experience could comment about that.
Anyway, RADB runs an IRRd server that is used to store each ISP
routing
policy, for example: what are your AS numbers, your networks, what
networks
you'll accept from ISP xxx or what networks you're going to
advertise to ISP
wwww (just two simple examples). You write your policy using a
specific
language (like an script) that can be used to configure the BGP on
your
NAP/MAE routers.
There are serveral IRRd servers and RADB.net host the "official" one
for the
US. RIPE has another server for Europe and some ISPs have their own
server.
I'm not sure why an ISP would want to have his own IRRd server, but
my guess
is that they probably use that information to know what are their
customers's BGP policies for them, i.e. what networks their
customers will
advertise for them so they can configure the BGP filters properly.
I know of at least one ISP that won't accept any advertisement from
their
customers unless register on the RADB IRRd server.
It's my opinion that since everybody can use the information on the
IRRd
servers as they want, it's always good to keep it up to date so you
don't
have somebody blocking your networks because you didn't register
your latest
policy there.
Good luck.

What is the use of RADB ?
Is it a must to register AS number and the route to the RADB ?
