Help on setting up a new block

Wed Mar 20 14:22:34 UTC 2019

     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.
