Due to our RIPE membership, the last ipv4-prefixes are changing to our own space. This also affects our dns-caches. Please make sure to check your servers configuration in order to use 220.127.116.11 (dns-cache1-ffm2), 18.104.22.168 (dns-cache2-ffm2) and 22.214.171.124 (dns-cache3-ffm3) as dns resolver. By 01th April 2019 we will take the old ipv4-addresses 126.96.36.199 and 188.8.131.52 out of service. Ignoring the changes could lead to connectivity issues.
Customers with Cloud and Dedicated Servers which were recently rebooted, may already use the new dns-caches. Please make sure your configuration matches the current standard.
