Hi,
I thought that you could try a different layout UI-wise for fitting more controls into a smaller area:
You could use a MenuBar for the program options, a SysListView for text information & Tabs for the various information types.
This way the Google Maps view will have its own tab with longer overflow sliders.
Having the option to capture the frame (IE ActiveX?) of the Google Maps page into PNG could be another interesting feature.
There could also be some icons on button controls & menu items.
Probably the famfamfam or silk icon packs will contain all the icons you need for an IP Geolocation user interface.
For the HTTP server info, you might want to spoof a basic web browser profile in a settings page where we could choose what to use as a custom User-Agent or other headers.
I think that the best way to display HTTP heades is to d it the debug-proxy way: two text fields with the raw HTTP request & the raw HTTP response with headers (you can omit response bodies, the most important part is to have the exact HTTP response up to the last header).
For the hostname (DNS info) tab, you could also add info for when a domain expires, when it was registered, what are the nameservers & its registrar.
If the user types a domain name for query avoid directly querying for it (even via DNS), first try to do WHOIS to see if it's taken.
Otherwise ISP DNS administrators can & do transmit their error logs to interested parties who might take the non-existent domain names (NXDOMAIN) for themselves.
Basically if the domain name doesn't exist in WHOIS, then just display a prompt telling the user that it's not possible to query it since it doesn't exist but they can try purchasing it.
I didn't try this software yet, I can try it later.
Nice to see that you're actually interested in the programs you make, that's a plus.
The best programs are the ones made by developers who acrually master the craft their program is made for.
For example a PCB design software is best made by developers who also have experience with making & ordering custom PCBs (circuit boards).
And as well IP lookup & location programs are best made by developers who understand well WHOIS, DNS & HTTP servers.
Just like flight simulators are best made by collaborating with actual accredited aircraft pilots during all stages of software development.
