I can't name specific ISPs with those featues, but I worked for an ISP at that time, and we tried to keep records maintained on three big lists of ISPs ... I can only remember one right now 'thelist.com' -- combined with the Internet Archive, and you can search for who existed back then

At least one of the lists also listed web hosting plans that the ISPs offered, and their features ... I just can't remember the name / domain for the other two lists ... does anyone else remember?

(it seems that Boardwatch had a list, but I don't remember using imagemaps to select, so I don't think that's one of the two I'm forgetting ... as they published hardcopy also, you might be able to find a back issue)

Update:

I think one of the other sites was isps.com, but they don't seem to have web hosting lists from that time period (I stopped working for an ISP in 1999, so I know they existed back then)
