I currently pay 70$ a month for residential 50/50 Ziply fiber internet in Oregon. On the ziply website it says it would be 50$ a month for 100/100 small business fiber. Would that let me get a static IP, port 25 unblocked and reverse dns? Are there any strings attached as it seems strange for small business internet to be cheaper than residential?
Not really. At least not where i live. For a small extra fee you can get a buisness connection at home. The speeds will let you go beyond what the normal home plans offer. Although you can still get 50/50 for buisness if you wish.
