Do a search on the /16 parent block. It has a history of being
on block lists. I imagine some admins have old lists that they do
not update very often, or have the entire /16 or greater blocked.
I also went through this process when we purchased IPs, and I've had
to contact hundreds of networks over the last couple of years to try
and get our blocks removed from their firewalls. Our specific
block was never on any block lists, but the parent was plastered all
over the place. <br>
<br>
It's potentially more difficult now than in the past because
there are some hosting providers that are simply a few people that
own VMs on some other infrastructure that they do not control or
have visibility into. The VM hosting company might be blocking your
network, and so the VMs never see your traffic. This means you
might contact Landstar, and then Landstar calls up their web person,
but the web person doesn't understand this stuff. The web person
phones his web hosting company who can't find anything wrong,
because they never see your packets to begin with. Now the web
hosting company (if you can get them to do this) needs to contact
their DC company that is hosting their VMs to find out if there is a
firewall or anti DDoS system etc that is sitting in front of their
VMs. <br>
<br>
Most of these calls take a long time. There is a lot of
hand-holding, and captures that need to be sent, and then you just
hope you can find someone willing to dig into it on the other end of
the phone. <br>
<br>
Good luck with the process. I believe you will be successful in
most cases, but it will take awhile. <br>

We recently went through an IP Broker and bought a /18 worth
of IP's<br>
<br>
I am listing all my information below. Should be public
record.<br>

RPKI Certified Yes <br>
<br>

<br>
In addition, I believe I got all the information in the IRR.
I am unclear on this part, but I do know ATT is happy now. I
can pass traffic through their network.<br>

So here is my problem. There are certain sites I can not get
to on the new ip block.<br>
<br>
<a href="http://clover.com" moz-do-not-send="true">clover.com</a>
- They are a large POS vendor catering to small business<br>
<a href="http://idrive.com" moz-do-not-send="true">idrive.com</a>
- Online backup<br>
<a href="http://heart.org" moz-do-not-send="true">heart.org</a>
- american heart association<br>
<a href="http://onlineproviderservices.com"
moz-do-not-send="true">onlineproviderservices.com</a> -
Looks like an outsourced group that handles medicare<br>
<a href="http://landstar.com" moz-do-not-send="true">landstar.com</a>
- trucking company<br>
<br>
I am working on trying to contact the companies above, but I
have started resorting to public shaming on social media. Not
an ideal solution.<br>
<br>
My thought, could I be missing something? Perhaps I need to
add a specfic entry in the IRR or anything? Just seems like a
lot of sites will not accept my traffic.<br>
<br>
Any experts like to chime in?<br>
<br>
