Hello Alex,
Here's one for the obscurities wishlist: our NetCaches don't recognise integer representations of IPs. Instead of interpreting 3263497985 as 194.133.7.1, for example, they look for www.3263497985.com.
Although nobody in their right mind would want to do this, people do use it when they want to obscure the tru source of a URL (yes, mainly in dodgy newsgroups, I know).
Later, Alex.
We, a while backt, had a bug open on this. However, after some study, it was decided to not turn the obscurity into a feature :-)
And, from the bug report..
Note that the "inet_aton()" routine in NetApp code was explicitly changed to require at least one "." in an IP address; the comment in the checkin was "error checking". That's why we don't accept dotless numbers as IP addresses.
Hope this helps.
Regards, suresh
