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.
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.
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.
Good luck with the process. I believe you will be successful in most cases, but it will take awhile.

I am unclear on this part, but I do know ATT is happy now. I can pass traffic through their network.whois -h whois.bgpmon.net <http://whois.bgpmon.net> " --roa 395437 138.43.128.0/24 <http://138.43.128.0/24>"0 - Valid ------------------------ ROA Details ------------------------ Origin ASN: AS395437 Not valid Before: 2019-02-13 05:00:00Not valid After: 2029-02-01 05:00:00 Expires in 9y318d10h46m2.39999997615814sTrust Anchor: rpki.arin.net <http://rpki.arin.net> Prefixes: 138.43.128.0/18 <http://138.43.128.0/18> (max length /24)So here is my problem. There are certain sites I can not get to on the new ip block.clover.com <http://clover.com> - They are a large POS vendor catering to small businessidrive.com <http://idrive.com> - Online backup heart.org <http://heart.org> - american heart associationonlineproviderservices.com <http://onlineproviderservices.com> - Looks like an outsourced group that handles medicarelandstar.com <http://landstar.com> - trucking companyI am working on trying to contact the companies above, but I have started resorting to public shaming on social media. Not an ideal solution.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.Any experts like to chime in? John
