I'm not sure what's unclear about that (unless you've just been reviewing some products for your website :-). But let's go over some basic concepts: 1) DNS information is stored in a file, so that Analog doesn't have to redo slow DNS lookups each time it runs. 2) Analog does DNS lookups one at a time, and they take however long it takes your DNS server to respond. 3) QuickDNS takes just as long as Analog to do a single DNS lookup, but QuickDNS can do multiple lookups at once (default=20) , so it finishes a lot faster. 4) Once QuickDNS resolves all the IP addresses in your logfiles, and saves the results in a DNS file, Analog can just read the answers, instead of doing any DNSlookups itself. Analog can't take advantage of QuickDNS's hard work unless you run QuickDNS before you run Analog. If you run QuickDNS on it's own, it tells you it's options. I use the following command: QDNS /D DNS.DNS /L logfile.log to create a DNS file, then add the following commands to ANALOG.CFG DNS READ DNSFILE DNS.DNS (I don't use the /G command to make QuickDNS lookup my .CFG file, because it doesn't always get what I want, especially if I use wildcards, or multiple logfiles). >Concretely, what steps am I to take to use QuickDNS? I can't honestly answer this question, because I don't understand what you could still need to know after spending 10 minutes experimenting with the sample logfile.log, QuickDNS and Analog.
