I'd always thought that this was kinda because of the way EPP is written -- not that it is actually required, but when reading the docs you see the nameservers object and kinda assume... I think at this point much of it is hysterical raisons. W On Thursday, September 11, 2014, Stephane

Vanity nameservers would not be very useful in DDoS mitigation (in terms of isolating your target) unless you actually create unique IP address nameserver records for each one. That's all you'll see in the attack, which IP's the attack is coming toward, not the hostnames of the vanity nameservers
