Boy have I got a story. 5gmesh is running on Time Warner Cable backbone. My father-in-laws ip is even in the same subnet as mine The system is quite simple really. It is a wireless 4 ghz lan link to 5gmesh receiver. the receiver is tied into a TWC residential modem. it is a natted connection that you would never be able to run inbound connections on. my ip is 98.*.*.130 his ip is 98.*.*.111. The funny thing is. He can have a static IP if he wanted to pay $10 more a month, whereas with TWC you are not able to get an static ip with residential.
Just because your IP Space is in the same /8 as his - doesn't mean 5g is using RR Residential Service.
I just found out that Residential Customers on TWC can get Static IPs. Although there is a catch and only available to certain customers. And if you wish to have a static, you must purchase them through an approved company. if you want more info, at this time, please PM me.
