You could start reading the logfile using a csv.DictReader:

header = ["site", "ip", "date", "method","code", "browser","n1", "n2"]

# dict to store [ip] -> occurences
# this defaultdict returns 0 for unset keys
ip_freq = defaultdict(0)

with open("filename.csv", mode="r") as csvfile:
    reader = csv.DictReader(csvfile, header, delimiter=",", quoting=csv.QUOTE_ALL);
    for line in reader:
        # sets the ip and increments the number of occurences
        ip_freq[line["ip"]] += 1
        # print: "requestcount: 2   ip: 85.97.166.82"
        print("requestcount: {}\tip: {}".format(
                                        ip_freq[line["ip"]], 
                                        line["ip"]))
