Verizon Business DSL static IP reverse lookup failed
Starting yesterday, the static IP address on our DSL line from Verizon no longer seems to be resolved with a host name. This caused several hundreds of our emails not being accepted by other mail servers (as their reverse lookup all failed). It used to have a PTR record like this: static-XXX-XXX-XXX-XXX.res.east.verizon.net.
the dsl gateway 18.104.22.168 we are connected to does not resovle either.
contacted verzion tech support, and they could not fighure it out. and they asked me to write to email@example.com.
Have anyone been affected by this DNS outage?
Okay, after calling verizon business support a few times today, I was able to get the troubleshooting ticket processed right away. They finally fixed the problem. They stated they had to add back the PTR record, but I doubt it. What had happened was likely the issue with one of their DNS servers, and they might just have restarted the server.
(when doing a nslookup, it was server error and not non-exsiting domain, which indicates it was DNS server error).
anyway, our emails started to going out....
