The network design requires unique IPs. The ran out of 10net in 2005 and have got a large part of 73net from ARIN. Their long term solution (new services = more IPs/customer) is IPv6. ----------------------------------------------------------- This was discussed earlier in the recent flurry of email on the subject. Also, this is why I was asking about VPRNs. However, I missed the part on why STBs need unique IPs or why they need 2 per box. scott
