downloading got different actually.
bcoz after the changes, basically the way it goes is u can imagine u no longer connect to internet directly.
rather, it's something like u connect to TM proxy (which share wit other users), then to internet.

if other people sharing the ip do something that makes the ip get banned, every1 in the ip get effected.
also, there's a small latency penalty.
& worst is, TM will hav more control over censorship edi.

yes.
it's like VPN.
u disconnect & reconnect, VPN assign u a new "local" ip.
but your traffic through public will always be that VPN IP.

the point is TM get to jimat public ip, at the same time assert more control over censorship.

if they like, TM can also splice bandwidth as they fit, & provide priority service as they fit.
ie, pipit all group 2gether into a crappy proxy, while helang get priority traffic.

i think u misunderstood the definition.
public ip is the ip assigned to u as ur identity on the internet.
got dynamic public ip (which changes when u reboot router),
& static public ip which remains the same even reboot router.

private ip is local ip for local identity.
ie, your router giv u ip192.168.1.2

in tm case, what they wanna do now is, they wanna treat customer as their "local" network.
now, public ip will assigned proxy layer, their proxy layer will assign private IP to u.

depending on situation, can b same or different also.
basically u can imagine like this.
u rent a room, the house owner controls the unifi modem & router.
when u plugged your PC in, the router assigned u 192.168.1.100, the next pc get 192.168.1.101, & so on depending in the DHCP pool.

well technically, it's dynamic, but usually if u disconnect & reconnect a while later, u'll b assigned the same IP given your DHCP lease not yet expiry & your previous ip not taken yet.
ip your previously ip taken, u'll b assigned next available slot.

yes, much like u put DHCP reserve on your router.
but, as far as i concern, there's no reason for TM to do so la, bcoz it only add complication wit no benefit for them.
basically they will operate like proxy provider.

actually, maxis fiber that is running on TM fiber has been doing this since the beginning.
u hav to actually call maxis to request for public ip.
from this i can tell u based on experience, the assigned private ip is dynamic.

this type is usually ip cam that comes wit subscriptions.
basically your ip cam feed goes to the cctv service provider server, u stream from their server.
this model not effected.

any traditional cctv/ip cam that requires port forwarding in routing will not work behind CGNAT.

everything is traffic direction only.
actually even wit CGNAT, it can work provided:

a) TM reserved your private IP
b) forward the same port traffic to your router.
& yes, TM actually has root access to your router via TR-069

in such case they dont hav access.
even the provider router, u can turn off TR-069, but provided u need to hav root access to the router.

the "admin" user that that provided is actually 1 step bellow the root or the superuser that the technician use.
this 1 u hav to ask the technician for the login during installation.

most likely this is the case.
as maxis has been doing for ages already.
all home maxis fiber goes behind CGNAT by default.
but if u asked, they will happily assign u public ip without asking much.

so fast kena edi?
TM service so cibai?
i suggest u MCMC their ass.
reply to their email say that u hav logged MCMC complain for TM breach of contract & providing favorable service to selective customers.

u know all these while maxis fiber also use CGNAT.
but they will giv u public ip without question if u just ask.

a quick "what's my ipv4" can reveal u're being assigned public or private ip.
private ip range is totally different & ez to spot.

services should not b effected, but there r consequences in sharing public ip.
maybe 1 idiot user in your pool that shared the same public ip wit u did something stupid & got the public ip banned, then every1 in that pool kena.
but there's little reason for VPN to banned their customer's ip cuz even they know most of their customers uses dynamic ip.

imagine this.

previously:
u got mobile number. 012-3456789
whenever outside people wan to reach u, call this number sure they know is u gonna pick up, cuz it's your cell.
when u cal out to people, they see this number, they also know is u calling.

now what TM wants to do:
u no longer hav your mobile number.
instead, u share a single company land line wit your colleague.
when u call to outside world, outside people only recognized this number is company A, but doesn't know who exactly is calling.
when outside people wanna call u pulak, will reach company receptionist first, then receptionist divert the call to your extension.
outsite people dunno your extension, only receptionist knows.

TM said browsing service is not effected, same performance.
that's a whole lot of bullshit & big fat lie.
u introduce overhead, delays, a point of failure cuz traffic need to jump through another layer to get to u.

now imagine, company introduce new rule, employee can only make approved work related calls.
u wanted to make a personal call to your wife to check on the kids.
receptionist says, "this number is your spouse's number, not related to work", & drops your call.

go figure.

i'm guessing:

1) they don't wan u to host anything using home package.
cuz hosting & things that require port forward no longer works.

2) they wanna assert more control, easier censorship.

3) they can splice the bandwidth, giving priority traffic to premium customers.
