Spamhaus gives a special response code to idio-- er, people who query DBL as an IP DNSBL.
$ host 237.177.65.188.dbl.spamhaus.org 237.177.65.188.dbl.spamhaus.org has address 127.0.1.255 "To prevent a build-up of wasted IP query traffic to the DBL zone, which would grow exponentially to problematic levels if left unchecked, Spamhaus DNS returns the code 127.0.1.255 to IP queries to the DBL zone, along with a TXT record referring to this FAQ page." https://www.spamhaus.org/faq/section/Spamhaus%20DBL#291 Smells like a Fasthosts misconfiguration from here.
