Answer to myself : NGNS is an internal component of the router (used to resolve well-knwon names, as far as I understand it), you do not need and cannot access it directly.

However, since switching to 14.06 things do not work as well as they where before, and I get many IpNameServiceImpl::SameNetwork(): Bad IPv6 network prefix: ER_FAIL errors in the log, I'll create another question about this issue.
