IP addressing questions

Will I get a static IP address?

All IP addresses (v4 and v6) are assigned via DHCP to home service subscribers. You are permitted 1 IPv4 address with the base package. Additional IP addresses may be requested for an additional monthly fee. Currently we offer up to 5 total IPv4 addresses on a residential package.

IP addresses are not "static" per se, but they do not change unless your MAC address changes or you let the lease expire (currently 3 days) and it is assigned to another user. So long as you maintain a connection with LightSpeed, your address should not change. 

Nearly every modern router supports Dynamic DNS functions, so if you have some need for a fixed IP and concerned there is a risk of your MAC address changing or being turned off through the 3-day expiration, Dyn DNS (or equivalent service) can be easily setup to map your IP to a domain name that will not change. 

Most ONT's have a single Ethernet port. To get multiple devices to accept multiple public IP addresses, you will need to plug in a switch between your ONT and router(s). 

 

Do you support IPv6?

Yes!

IPv6 prefixes are assigned to your router via DHCPv6-prefix delegation. However, consumer routers support for IPv6-PD is just emerging and we have experienced interoperability concerns. Your mileage may vary! LightSpeed support is expanding as we work through all of the vendors quirks regarding how they operate with DHCPv6.

The routers that we have tested with IPv6-DHCP-PD include Apple Airport Extreme (latest generation), Netgear Nighthawk, ZyXEL and ASUS. 

Due to interoperability issues with some consumer routers, we enable IPv6 only upon request. If you would like IPv6 enabled on your port, please email help@golightspeed.com.

Set your router as follows:

Connection Typer: Native

DHCP-PD: Enable

Stateless IPv6 LAN / Auto configuration

IPv6 DNS setting: Enable automatic connection to DNS server

Router Advertisements: Enabled / Yes

    My D-link gigabit wireless-N dir-827 worked out of the box with IPv6 and DHCP-PD. only problem I have with it, is, no matter what i type in for local domain name, it still advertises golightspeed.com by DHCP.

    I was just commenting on the fact that you got those routers to work, and I am saying the d-link router does too.
