1. SingTel : pretty complicated
Public IP: yes, no static add-on
SingTel provide same connection for Internet and Fibre TV, vlan is needed. For ONR users, Vlan is handled by the ONR.
SingTel 1+1Gbps plan, the ONR will be configured as three port ONR and one port ONT, I believe that ONT port does not require vlan.
Certain users have asked Singtel to provide a special configuration for the ONR, three ports for SingTel TV only without internet access, one port ONT without vlan.
2. Whizcomms
Public IP
Whizcomms provides ONR, but you can ask them to configure the ONR in ONT mode prior to installation without charges. No Vlan needed.
3.M1
Public IP, ONT, no vlan needed.
4.Starhub
Public IP, ONT, no vlan needed.
Starhub uses different ONT ports to deliver Fibre Internet and Fibre TV.
Starhub 2Gbps plan: ONT port 1 and ONT port 3 used to deliver 2x1Gbps connection, ONT port 2 for Starhub Fibre TV
Starhub IPTV users, if need to mix internet and IPTV through same connection, special vlan configuration will be needed.
