I’m wondering if some can share their experiences or maybe there’s an AT&T person here who can confirm policy. I work for SaaS provider who requires a source IP to access our system to businesses.
That is probably a problematic practice.
Normally we tell the customer to request a “Static IP” from their provider. That term makes sense to most ISPs. However, we’ve recently worked with an AT&T higher-up tech who told us that every U-Verse modem is locked to an address even when set to DHCP and will not change unless the unit is changed. Ordering a “Static IP” from them means your devices will individually get public addresses, which isn’t a requirement for us, isn’t quite as easy to add multiple devices and costs our customers more money. Here are my questions: 1. Is it really accurate that the customer’s address is tied to the modem/router? 2. For my curiosity, is this done through a DHCP reservation or is there a hard coded entry somewhere? 3. Do all U-Verse modem/routers behave the same way? This particular unit was a Motorola but the friends I’ve seen with U-Verse use a Cisco unit. --- Keith Stokes
AT&T addressing has been detailed here in some ways. I am not sure how accurate it is or at what state this has been deployed http://www.networkworld.com/article/2188898/lan-wan/at-t-demands-we-change-our-networks.html But, it is possible that AT&T does not have IPv4 static addresses to assign.
