Sorry to hear your legitimate users are impacted by captchas when trying to use Google web search. This can happen when you have significant amounts of abuse coming from your network. If switching to IPv4 means having more users share IPs, it could make the problem worse. Instead, let's try to quickly address the IPv6 issue. Please send me your IP allocation policy (off-list is fine). For example (guessing from the list at http://bgp.he.net/search?search%5Bsearch%5D=netassist&commit=Search): - 2a01:d0::/32 is allocated by /48 - 2a01:d0:8000::/33 is allocated by /56 - 2001:67c:1874::/48 is allocated by /64 - ... etc (IPv4 allocation is appreciated as well, if you also provide customers with large ranges there) I can then give that hint to our automated abuse systems, which will both make it easier for us to catch your abusive customers, and also to avoid over-blocking of your AS.
Hi,just curious. Do you support the RIPE object called "assignment-size" automatically?
https://apps.db.ripe.net/search/lookup.html?source=ripe&key=2001%3A980%3A3000%3A%3A/36&type=inet6num for instance, indicates that each customer in this /36 is a /48. Do you pick this up automatically and hint your abuse system about this? Does it send automatically generated abuse reports to the abuse contact as well?
