How to block Yandex using IPTABLES or APF

Re: Yandex IP range, Yandex subnets, Block Yandex Robots

Across our server range we are finding that Yandex continues to ignore robots.txt files and crawls some sites constantly, so how do you stop such an abuse of your network resources?

If you use IPTABLES or APF (you should!) then you can block all Yandex spiders using the following IP ranges:

77.88.0.0/18 # yandex.ru
77.88.22.0/23 # yandex.ru
77.88.24.0/21 # yandex.ru
77.88.24.0/22 # yandex.ru
77.88.28.0/22 # yandex.ru
77.88.36.0/23 # yandex.ru
77.88.42.0/23 # yandex.ru
77.88.44.0/24 # yandex.ru
77.88.50.0/23 # yandex.ru
87.250.224.0/19 # yandex.ru
87.250.230.0/23 # yandex.ru
87.250.252.0/22 # yandex.ru
93.158.128.0/18 # yandex.ru
93.158.137.0/24 # yandex.ru
93.158.144.0/21 # yandex.ru
93.158.144.0/23 # yandex.ru
93.158.146.0/23 # yandex.ru
93.158.148.0/22 # yandex.ru
95.108.128.0/17 # yandex.ru
95.108.128.0/24 # yandex.ru
95.108.152.0/22 # yandex.ru
95.108.216.0/23 # yandex.ru
95.108.240.0/21 # yandex.ru
95.108.248.0/23  # yandex.ru
178.154.128.0/17 # yandex.ru
178.154.160.0/22 # yandex.ru
178.154.164.0/23 # yandex.ru
199.36.240.0/22 # yandex.ru
213.180.192.0/19 # yandex.ru
213.180.204.0/24 # yandex.ru
213.180.206.0/23 # yandex.ru
213.180.209.0/24 # yandex.ru
213.180.218.0/23 # yandex.ru
213.180.220.0/23 # yandex.ru

Simply restart APF and Yandex will no longer be a problem (until they extend their network!).
