Do I Need A Dedicated Ip?

[das]

I have a TCH reseller account with several domains on it. One client is switching to an on-site mailserver, and since their uplink is dynamic, they will use a DNS service from DYNDNS.ORG to map their MX and other DNS records.

 

I've searched TCH's help and forum areas, but it's still unclear to me whether my shared server will correctly handle requests if the dyndns.org nameserver simply resolves to 69.57.134.37. Currently, I can get to the site using http://69.57.134.37/~hrtt which then resolves (forwards?) to http://server30.totalchoicehosting.com/~hrtt

 

But I need to keep the client's URL: www.hudsonrivertruck.com intact. Do I need a dedicated IP so that the IP alone will:

(1) work with dyndns's DNS servers and

(2) stay set to www.hudsonrivertruck.com ?

 

The domain is currently hosted somewhere else but I hope to move it to TCH this weekend.

 

Thanks,
