clients of certain isp cannot connect to my sites
Hi
I have a problem which I'm sure is common, it just has to be! Here's the specs of the problem, numbered so I don't forget anything:
1. I have a managed dedicated server ip 66.195.19.200 where I have all my sites hosted.
2. One particular isp prexar.com cannot resolve anything at that ip. Neither anyone that works there nor their clients connected to the isp can view my websites nor engage in any email in or out with my client's sites hosted on my server. i.e. if my clients are using their website as smtp and pop they cannot engage in email with any clients of prexar.com isp.
I think that's it. my nameservers are squeaky, I have rDNS, we're down to it being a router or network issue but the isp has informed me that it cannot be them, and I tend to believe it as they have checked everything. Does this sound familiar to anyone?? What are the possibilities os I have some "ammo" for either my web hsoting provider or the isp in question??

Some countries/regions block by location. Japen for example has a strict no porn policy and tends to block a lot of IP addresses. Some times if the servers are at the same data center they can be blocked by mistake.
Can be a lot of little things, sometimes even firewall/antivirus programs can block IP ranges, I think it was NAV 04 that is bad for that
