Re: DDOS Attacks - Is Any VoIPP More Immune ?

said by Davesnothere:

to pose the question regarding which (if any) VoIP provider's topology and infrastructure might allow them to better endure/repel being 'next',

In theory it is possible for a provider to be less vulnerable to DDoS attacks. But most residential customers would be very unhappy.

For incoming calls:

• Customers are not allowed to register a SIP device or a softphone.

• Incoming calls can only be forwarded to a SIP address or a PSTN number

Forwarding of Callcentric inbound calls to a SIP address has been working very well during this attack, not a single missed call.

For outgoing calls:

• Customers are not allowed to register a SIP device or a softphone.

• Outgoing calls can only be set up to a SIP address or a PSTN number using a Click 2 Dial feature.

Without SIP device/softphone registration it would be a lot more difficult to launch a successful DDoS attack on a provider.

But as long as we are stuck with IPv4 this solution will not work for most residential users.

Arne, does IPv6 help this problem?

---------------------------------

Although getting to the promised land of IPv6 may require both:

a) Another Moses.
b) Another 40 years in the desert.

The US government has badly missed their own deadline last week for IPv6 on their websites.

With IPv6 it's likely the customer will have a unique static public IP address for his SIP device, thus avoiding NAT issues.
