Which lookup tool query both hosts and DNS server?
As i understand, host/nslookup/dig only query DNS server to resolve name to ip.
ping can query both, but it seems if ping is blocked, ping won't return IP.
traceroute can query both, but i am not able to test if traceroute is blocked, What is the result?
Neither ping/traceroute is decent tool to do the job,any other ideas?

traceroute6.iputils
TRACEROUTE6(8) System Manager's Manual: iputils TRACEROUTE6(8)
NAME
traceroute6 - traces path to a network host
SYNOPSIS
traceroute6 [-dnrvV] [-i interface] [-m max_ttl] [-p port] [-q max_probes] [-s source] [-w wait time] destination [size]
DESCRIPTION
Description can be found in traceroute(8), all the references to IP replaced to IPv6. It is needless to copy the description from there.
SEE ALSO
traceroute(8), tracepath(8), ping(8).
HISTORY
This program has long history. Author of traceroute is Van Jacobson and it first appeared in 1988. This clone is based on a port of tracer-
oute to IPv6 published in NRL IPv6 distribution in 1996. In turn, it was ported to Linux by Pedro Roque. After this it was kept in sync by
Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>. And eventually entered iputils package.
SECURITY
tracepath6 requires CAP_NET_RAWIO capability to be executed. It is safe to be used as set-uid root.
AVAILABILITY
traceroute6 is part of iputils package and the latest versions are available in source form at http://www.skbuff.net/iputils/iputils-cur-
rent.tar.bz2.
