Continuation of the Server Farm threads.

This is where we report data center IP ranges as they are discovered or change in the rapidly evolving assigned IP landscape.

rtcomm also acts as an ISP for businesses, so no, not the entire /15, just the bad actors on some sites. On other sites entire RIPE is nuked, but the request data is still collected :).

New for me as well, thanks blend27! but that CIDR only covers 54.37.0.0 - 54.38.255.255 - is the 54.36.0.0 - 54.38.255.255 range a typo?

@not2easy - the entire /16 is indeed OVH

Some look-up tools are better than others... some better for some regions... or some may not update their info often enough... and ranges get expanded, sold, repurposed, etc.

If you see only a partial range listed, often you can discover the full range by testing one or two sub-levels up or down. Sometimes the way these ranges are listed are because of the way they were leased or expanded.

My current favorite online look-up tool is: DomainDossier [centralops.net]

I can see that the entire 54.37.0.0/16 range is OVH, my question was about the listing of 54.36.0.0 as the beginning of it with only a /16 to go from 54.36.0.0 o 54.38.255.255

I did a lookup on the range excluded from that CIDR and it seems that is also OVH but not included in that 54.37.0.0/16 CIDR - it would need a separate 54.36.0.0/16 to go with 54.37.0.0/16

My quick choice is the Network Tools built in to OSX. Occasionally I need an outside check for sub-ranges.

Ahh.. I see, sorry not2easy.

So when I looked, I saw even a broader OVH net block of:

54.36.0.0 - 54.36.255.255
54.36.0.0/16
54.37.0.0 - 54.37.255.255
54.37.0.0/16
54.38.0.0 - 54.38.255.255
54.38.0.0/16
54.39.0.0 - 54.39.255.255
54.39.0.0/16

which can be reduced to:
54.36.0.0 - 54.39.255.255
54.36.0.0/14

Note: there are hundreds of private customer accounts, small companies, and who knows what else in there so if blocking without prejudice, keep a close watch of what exactly gets blocked.
