What asset class should I use for an e-commerce website? I assume it is a section 197 intangible asset, but I need to declare if it's class V, VI or VII.

I have sold my business (asset sale) and am filling out Form 8594. Part of the business sale is the e-commerce web site. What asset class should I use for the website? I assume it is a section 197 intangible asset, but I need to declare if it's class V, VI or VII.
