SNMP over IPv6 is not working

I have a box configured with dual-stack (See below). Also installed "A.11.00-011 HP-UX Internet Express" bundle. I also switched to use Net-Snmp agent. I can snmpwalk to its IPv4 address 15.2.127.255, but when:
# snmpwalk -c public -v 2c udp6:2620:0:a07:e402:21a:4bff:feab:9e92
getaddrinfo: host nor service provided, or not known
Timeout: No Response from udp6:2620:0:a07:e402:21a:4bff:feab:9e92

Here is my latest progress. Actually still same. I modified /opt/iexpress/net-snmp/etc/snmp/snmpd.conf to include the following configuration with the rest untoughed:

"####
# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):

# sec.name source community
com2sec local localhost public
com2sec mynetwork 2620:2::/64 public"

Then I restart the snmpd but got the following error. Seems it does not recognize the IPv6 address:

# /opt/iexpress/net-snmp/sbin/snmpd udp6:161
/opt/iexpress/net-snmp/etc/snmp/snmpd.conf: line 62: Error: bad source address
net-snmp: 1 error(s) in config file(s)
getaddrinfo: host nor service provided, or not known
NET-SNMP version 5.4.1.2
