Hi, I was wonder what’s the advantages and disadvantages of enabling public IP on maxis fiber internet, other than hosting CCTV/ remote websever?

not sure about Malaysia , dynamic ip will change every 6 months in Singapore

static IP will stay forever for you, if u using CCTV , recommend using DDNS from the CCTV system

dynamic normally cheaper then static ip

That's about the gist of it.

He's asking about private vs public, not dynamic vs static. In Malaysia both private and public IP are dynamic unless subscribe business package with fixed IP. The dynamic IP changes everytime you make a connection (turn on router).

For private vs public IP, there shouldn't much difference if you don't do anything that requires direct access to your home network from the Internet. If you need to such as CCTV and hosting then public IP is a must. Other than that, the only thing is probably some sites may block you or present captcha on private IP since it detected alot of connections from the same public IP that many private IP users are sharing.

but private IP is internally only.. not for external access , as he mention want to hosting cctv or webhosting

Private IP means the router WAN IP is in the private IP range. This is because the ISP ran out of IPv4 addresses and therefore made several customers share the same public IP. Basically it's like a double NAT connection. You can't host anything with this type of connection because there is no public IP that can directly route to your router.

Public IP:
Internet----- (public IP) home router (private IP) ------ internal home network

Private IP:
Internet-------- (public IP) ISP router/NAT-------- (private IP) home router (private IP) ---------- internal home network

You might need to check on CG-NAT

You are the only one that made sense in this thread with readers to your explanations.

Meanwhile, if one opts for IPv6.....better pray all devices have proper IPv6 firewall in place. All direct point-to-point connectivity with IPv6.
Last time, NAT 'accidentally' act as filter/firewall for IPv4, with IPv6....hmmm.....unless one can configure NAT-ed IPv6....... but it is pointless in first place.

Well, IPv6 is supposed to get rid of NAT requirement. Some routers like Asus have a properly working IPv6 firewall. It's a firewall not a NAT. Blocks incoming connections but doesn't change the address.

Is there any speed/reliability/latency/responsive benefit to opt for a public IP?

Public IP has 1 level of NAT.
Private IP or CG-NAT has 2 or more levels of NAT.

Other than CCTV (the ones which need ports forwarded) or remote web server, not good for torrents. Also Playstations or other game consoles will give a lower grade for your NAT test.

For the end-user public/internal IP doesn't have any disadvantages. Some say it's safer. That's BS. proper setup firewall it doesn't matter anything if you have internal or public IP.

btw private IP doesn't exist, unless you own the IP, which you can't. You can purchase the IP from services that "own" the IP only for a limited time. IP's are like ground in Malaysia. You can buy it for a specific amount of time, but you can't own it. Nor do these services actually "own" it.. They are just appointed proper delegation.. internet is tricky but basically no one "owns" anything.. it's regulated and maintained by companies that "sell" their "services and regulation" to you, ISP, web-host and other companies but no one really "owns" anything.

So just as much as "private" land doesn't exist in Malaysia things like "private IP" don't exist either.

It's public IP or internal IP of the internal network with a shared public IP.

Neither case it's private. Best case it's rented and giving to you the authority to decide what to do with it, but it's never truly "owned"
and thus never truly "private"

Yes some might argue:" sure you have private land in Malaysia" that's topic of interpretation. You basically bought the rights for the land
to manage it for 99 years. Included in this "managing rights" is your right to decide who might enter or not. So you might argue that's "private"
but since you don't "own" it, but only "rented" it, it's not really yours anyway and thus as such it's not really "private" because the government
can always just change the plans and then you loose your ground to a "public" authority, which is the government, state, whatever.

Anyway, back to Networking, NAT doesn't make your network safer nor does NAT from your ISP make you safer nor is anything here private
either. Your hardware at home may be private. Your ISP hardware may be private. But no one can really "own" the IP or other protocols and their
associated variables like an IP address.

biggest security leak for 99,999% of the people is they are logging into their computers every day using an account with elevated/administrator rights.

Just visit the wrong website, open the wrong email, open the wrong USB stick and that's it, gone is your security and programs in the background without you knowing it are now executed with full rights to do whatever they want to do on your system.

So there's no negative thing from having a public IP.

The benefits are easy to spot: not hosting anything? No benefits!

Want to host any service for yourself? You can open a specific port for that service on your local router and it works.

With a shared public IP and internal IP behind it of course this hosting of services doesn't work.

That's the only real benefit.

Since the vast majority of the people have no clue how to host any service, they won't need it.

And those that want to host a service, even if it's just a game server for a private group of friends, just call your ISP and within 10 minutes you got it up and running.

Reboot your router though.
