[dns-operations] NS1 nameservers response size

[Jan Včelák]

Hello,

I can confirm we do not respect the buffer size. We are aware of this
deficiency but it also doesn't have high priority at the moment.

Have you encountered a situation where it has been causing trouble for a
real application? Or is this an accidental discovery?
