Thanks Mel.

The ISP got back to me and has asked me to build a Juniper block list ACL for 
them so I am doing that now.

Blackholing isn't what you want. That will still permit his source IP into your 
network, and only blackhole replies from your network, so the attack will still 
consume bandwidth. What you should request is a source IP ACL blocking that 
address at your upstream' border.

BGP is no help in these situations, unless you use a BGP-based DDoS protection 
service.

Thanks Mel.  You are not being difficult, I meant DoS.  The network I inherited 
doesn’t have BGP yet so I have asked our upstream to blackhole it and I emailed 
abuse neither have happened yet.  I do block it but that’s after it hits our 
side.

Not to be difficult, but how can it be a DDoS attack if it’s coming from a 
single IP? Normally you would just block this IP at your borders or ask your 
upstreams to do so before it consumes your bandwidth. You still want to get 
GoDaddy to address the problem, of course, but you should do that via their 
ab...@godaddy.com<mailto:ab...@godaddy.com> contact, or their abuse page at 
https://supportcenter.godaddy.com/AbuseReport/Index (submit via the “malware” 
button).

My company is being DDoS'd by a single IP from a GoDaddy customer.

I havent had success with the ab...@godaddy.com<mailto:ab...@godaddy.com> 
email.  Was hoping someone
that could help might be watching the list and could contact me off-list.
