as51430.net spammed me, so here is the research for tracking and banning. as51430.net is out of Luxembourg. I did not get spammed by its three sister host names, lux-net-ip.as51430.net, nld-net-ip.as51430.net, and swe-net-ip.as51430.net.
Observation:
lu-customer-ip.as51430.net found the following IPs:
Research:
Further research found the following host names that change often: lux-net-ip.as51430.net, nld-net-ip.as51430.net, and swe-net-ip.as51430.net. Maybe they stand for Luxembourg, Netherlands, Sweden? Here is the complete list by ip address, so you can ban all three.
Dell Inspiron Mini IM10v 1011, memory upgrade to 2G really made the difference. Processes are runnig much faster now.
My Aunt gave me this tiny 10″ mini laptop, running Win XP, that simply would not even boot up properly. I spent the time to clean it up, and it cleaned up pretty good. Still it was running very slow, even after killing off many unneeded processes, so I decided to upgrade the RAM from 1G to 2G. It really makes the laptop bearable, if not snappy.
22110.s.t4vps.eu spammed me. Though they resolved a host name to 194.135.93.53, there was scant info on this host name, so I researched them. I do not see a pattern.
no.rdns.ukservers.com content spammed me, so I researched them. They have a sister host name, no.rdns-yet.ukservers.com, with very much the same ip ranges. See for yourself. They are industrious in their use of IPs.
bezeqint.net content spammed me, so naturally I researched them. They are very smart, these Israelis, and employ a variety of anti-bot software techniques, in order to evade identification. Hats off to them for deploying these tactics. I hope they keep up the good work.
Pattern:
This ISP employs 3 patterns, inter-dispersed within their Ip ranges. You need to differentiate between these three or you will ban the incorrect IP range.
red: reverse first 3 octets, add 4th
red, static.dcenter: straight 4 octets
cablep, red: host name has 3 octets, special number for first octet
reverse.completel.fr gave me some error 404s, so I thought to look them up. This research excludes reverse.completel.net. Be careful here because though you could ban the whole /16 range you would exclude a whole bunch of French people, and that would be bad.
ioflood.com piqueted my interest in their novel hostname: we.love.servers.at.ioflood.com. This turned out to be a barrage of IP addresses, something I did not expect.
Mulberries, we have in the backyard, compliments of our large black mulberry tree. With it comes the mulberry mess. Well, you either frown or you make the best of the situation. In this case: mulberry sorbet.
It started as a sproutlet at the side of our house. I was unsure if it was actually a mulberry as there were 3 or 4 different types of leaves growing from the same plant. I thought it was, so transplanted it to a sunny location and waited 4 years until it started fruiting. It has been going strong ever since.
