I'd be interested in applications around ownership of IP space or ASNs, but
there's so many ways to skin that cat already that people don't do because
it's 'hard' or 'reduces our flexibility' or sometimes because it involves
hardware upgrades as Christopher Morrow pointed out with RPKI and BGPsec.
Have you configured RNAT yet? Might tidy up your SIP problem. Do you need
the servers to see the client's source port, or is your issue that SIP
response traffic is not on the port the client expects?
Give the guide to setting up RNAT here a try -

The correct prefix and pingable address list for the Debogonising Project is:

Hello,
If anyone has a contact in the Google Group that deals with Google's

Hello,
Is anyone seeing any EC2 issues? We started seeing them as of about 9:01am
today. The issues are manifesting with different instances sporadically not
being able to connect to each other or connect to hosts ourside EC2.
Thanks,

If you're staying Cisco, probably the ASR1000 series, or the ASR9K,
depending on needs.
You probably don't need CSR routers if you're not going to 100Gbps.

So I don't think they can charge it based on whether it is full routes

They may charge for running BGP with you, but not for full routes or not.

Cisco 7304 may not adequate for service provider.
It's CPU/IO-controller is tied together, and doesn't provide much of
benefit.
Cisco 7200/7300 is enterprise solution pretty much, and doesn't support
distributed CEF.
If you are considering SUP720-3BXL, why not considering RSP7
you need OC3/12/48, you can have those with additional license fee.
Foundry router price is a lot lower than Juniper MX series router.

Because of nowadays network scalability demands, Cisco is preparing ASR
14000 series to replace this one, I think. ^^
Basically ASR 14000 is downgrade version of CRS-1, but I consider it is
still developing or beta product.

It really depends on your application server configuration.
Most people just uses SNMP for this purpose.
Something like net-snmp installed in servers, then monitor the info via
SNMP MIB polling.

What if there is a problem from software, filter, mis-configuration from
one of the routers ?
It will affect whole ring network, not just that problem router.
Also if there is routing protocol bounce because of link flapping, it
will be propagate through the ring forever.

If there is DDoS attack going on from/to specific /32, sometimes they do
that to avoid too much overload for the network.
Cogent should give the answer for what's going on.

I think it is really depending on what kind of provisioning system you
have.
Circuit ID is determined by your provisioning system for CLR/DLR reference.
As long as you can find circuit info quickly, it doesn't matter that much.

Theorically it's doable.
But mostly No to your questions.
IXP means Internet eXchange Point.
So it is public Internet. Why do you want to use private IP address ?
Most RIR allocate /24 unit for IXP.
For troubleshooting purpose, it is better to use public IP address as it
is designed.
