Thanks, but I think it's easy enough for you to rsync a copy of CBL or other DNSBL zones and grepcidr through it for your own netblocks, so I'll just continue as I am. I appreciate the offer, though, and don't doubt the sincerity. I just don't have time to police your networks for you, much less everyone else's. >> Unfortunately, it's not.

And do all of your statically assigned internode.on.net PTRs contain the token 'static'? Or not? If not, why not? In any case, do you provide custom PTRs for those who ask? If so, why not provide them for /all/ customers with statics? The hosts with 'padsl' tokens - are they all NAT/VPNs (Private Access DSL, a la THUS) , or just "Personal ADSL"? Are your hosts with ppp tokens dynamic, static, or a mixture? I see both types; hosts wstarting with 'ppp' and containing a 'static' token, and others without. Martin Barry mentioned 'LNS' as a big giveaway as to the sort of nodes those are, and suggested that they're infrastructure devices which would never send mail, yet in the past couple weeks we've seen connections from the following hosts: ppp121-44-233-193.lns1.per1.internode.on.net ppp118-208-178-233.lns10.mel4.internode.on.net ppp224-33.lns3.syd7.internode.on.net ppp121-44-110-124.lns10.syd6.internode.on.net So I guess they're not that sort of device. <shrug> Under Technobabble on the Web page above, you specify which services are usually static and which dynamic, making distinctions between Home, SOHO, Corporate and so forth, but your naming doesn't reflect those distinctions. (Think Road Runner, who uses res.rr.com for nearly all of their home cable hookups, and biz.rr.com for their business cable).
