I am trying to lock down a web server PHP directory to just source IP addresses originating from Linden Labs (llHttpRequest() calls). Has anyone narrowed down the IP address range for these?

These address ranges are listed on the LSL wiki (http://lslwiki.com/lslwiki/wakka.php?wakka=llEmail) for IP address ranges for the llEmail command:

66.150.244.0/23
69.25.104.0/23
72.5.12.0/22

If I've observed the behaviour of llEmail and llHTTPRequest correctly, those address ranges should be valid for HTTP requests as well as email.

You never know when they'll add to the cluster on you... how about locking it down to just LL's IP blocks? I think those've been posted here before.

Use a reverse DNS lookup.

Use a reverse DNS lookup.

in case u hadnt relised that there are multiple servers with diff IP's
depending on where and when u log in it grabs the closest one
if the closest one is busy having com problems ect it auto routs
depending on how much bandwith you have acess to it could bounce u to another continent for the best connection (only happend once... so far )...
best to find it once your connected.

WTF does that have to do with the price of tea in China?

Nothing at all I imagine - the IP addresses of the sims making the HTTP request and the IP addresses of the servers that the clients connect to do not seem to have any correlation.

Using DNS lookups could work, however that's extra time that the web server has to spend processing the incoming request (as it would have to do a gethostbyname call on each incoming request), it's much easier to narrow it down by IP address ranges.

The ones I provided should work - I'm looking at http requests made by one of my test objects in Discordia sim, it's coming from one of the IP's in the 72.5.12.0/22 range right now
