The problem seems to exist in the 173.246.96.0/20 block of AS29169 (173.246.96.0 - 173.246.111.255), a range of IP addresses that houses very many legitimate domains. Unfortunately, it also houses several malicious servers in the 173.246.102.0/24, 173.246.103.0/24 and 173.246.104.0/24 ranges, alongside legitimate sites.
First of all, let's look at the warnings I have given about this IP range just in this blog alone (ignoring all external sources):
173.246.101.146 |
CNN "Harrison Ford" spam / 173.246.101.146 and fragrancewalla.com |

173.246.106.150 |
"Scan from a Xerox WorkCentre" spam / Scan_06122013_29911.zip |
So, curious about how bad the situation was I went off to identify servers currently hosting malware, and the list I came up with was:
173.246.102.2
173.246.102.202
173.246.102.223
173.246.102.250
173.246.103.47
173.246.103.191
173.246.103.232
173.246.104.52
173.246.104.55
173.246.104.104
173.246.104.128
173.246.104.154
173.246.104.184
173.246.104.185
That's quite a concentration of badness. You can see a full list of the malicious domains, WOT ratings, Google prognosis and SURBL codes here [csv]. There's a plain list of domains at the end of the post for copy-and-pasting.
Now, normally I would recommend blocking at least a /24 when dealing with this sort of level badness, but as this overview of the /20 shows [csv] there are a load of legitimate sites interspersed with the malware. Of course, you may want to block chunks of this IP range anyway and live with the collateral damage.. if you are hosted in this range then I suggest it is time to look for a new host.
Over the past 12 months there have been at least 25 malware servers in this block, with 173.246.102.0/24 hosting 5, 173.246.103.0/24 hosting 8 and 173.246.104.0 hosting 9. Something must be seriously wrong at Gandi to allow this to happen.
