Reliability of a /24

["Timothy J. Massey" <]

Hello!

In 1995, I was assigned a Class C network.  In 1995 I used it, but in
1998 my organization moved out of state.  When we set up our Internet
connection at the new location, we just moved forward with using the
addresses given to us by our ISP.

Today, our ISP doles out IP addresses out with a teaspoon and charges
fairly serious money for more.  We would like to begin to use our /24
network instead of dealing with getting more addresses from our ISP.

In addition, we want to connect our network to a second ISP and begin
broadcasting our routes via BGP.  The problem is, with the change to
CIDR, it seems that /24 networks are unappreciated.  ARIN states that
any network smaller than a /20 is not guaranteed to be globally routed.
 Yet other sources seem to suggest that most (but not all) /24's should
be OK.

We don't want to switch to the /24 if that is going to give us routing
problems.  In my search for information regarding this, I came across
your e-mail address on a Web archive of a mailing list.  You seemed to
have an understanding of this issue.  Could you please point me to a
somewhat more difinitive source of information regarding this I would
greatly appreciate it.

I am sorry for the unsolicited e-mail.  I will not send another (unless
you are kind enough to reply!).

Thank you very much for your time.
