From pen homepage:
"This is pen, a load balancer for "simple" tcp based protocols such
as http or smtp."
As I know DNS uses both tcp and udp protocols.
From the posters excerpt it looks like they are looking to load
balance HTTP. [1]
For failover you can try OpenBSD Packet Filter with CARP protocol. PF
can do load-balacing using different algorithms also. CARP is ported
to FreeBSD. More info on: http://pf4freebsd.love2party.net/carp.html
Also true. Last time I looked at this however there was a big
disclaimer saying that
CARP's load balancing was likely to give a distorted distribution of
load and I don't
believe it does weighting. I believe this would also be a problem
considering the
example in [1]:
From carp(4):
Note: ARP balancing only works on the local network segment. It
cannot
balance traffic that crosses a router, because the router itself
will
always be balanced to the same virtual host.
Cheers,

Yes but the idea here is to use http balancer that runs on CARP
interface(s) for fail-over.
Balancing will be done by balancer ;)
