Yep,
To quote the drbd.conf manual :
http://www.drbd.org/users-guide-emb/re-drbdconf.html
[...]
address AF IP:port
A resource needs one IP address per device, which is used to wait
for incoming connections from the partner device respectively to reach
the partner device. AF must be one of ipv4, ipv6 or sci. It may be
ommited for IPv4 addresses. The actual IPv6 address that follows the
ipv6 keyword must be placed inside brackets.
Each DRBD resource needs a TCP port which is used to connect to
the node's partner device. Two different DRBD resources may not use
the same IP:port combination on the same node.
[...]
Not sure if it is present in any of the tutorial.
