Hi sifus,

Just curious, is there such thing as ' best IP range ' for UniFi ? i.e. in terms of connection reliability, international routing, etc. ?

I've read that some ISPs use different routing tables based on the IP range. Eg. Singapore MyRepublic

I've seen people claiming some UniFi IPs perform better than others, but they never gave any definitive proof or facts, just thoughts and opinions.

I've also tried to find out for myself. Even if it's true, I honestly never noticed any real difference.


Here is a (mostly complete) list of UniFi IP ranges that TM assigned to my router from October to December 2019. I live in PJ area, subscribed to UniFi 500 M, using C1200 V1, with ipv6 enabled.

Note : * Not confirmed


- 60.48.x.x
- 60.49.x.x (contributed by cba5566)
- 60.50.x.x
- 60.53.x.x

- 110.159.x.x

- 115.132.x.x
- 115.133.x.x
- 115.134.x.x
- 115.135.x.x

- 118.100.x.x
- 118.101.x.x

- 124.13.x.x

- 175.136.x.x
- 175.137.x.x
- 175.138.x.x
- 175.139.x.x
- 175.140.x.x
- 175.141.x.x
- 175.142.x.x
- 175.143.x.x
- 175.144.x.x
- 175.145.x.x

- 202.188.x.x

- 203.106.x.x

- 210.186.x.x
- 210.187.x.x (contributed by cba5566)
- 210.195.x.x (contributed by cba5566)

*- 218.111.x.x (contributed by cba5566)
- 219.92.x.x


P.S. Previously, I used to get 210.186.x.x and 210.195.x.x series, but no longer these days. All TM ipv6 addresses start with 2001:e68:: prefix.

Pls add 210.195 , 60.49 and 210.187..... for unifi.

218.111 not sure unifi provide it.
Last time used to be stimyx connected.

Sure, no problem, I'll add to the list

Well, for me I always test it with SG Singtel server, it gives me the biggest different in ping time, some IP gets me about 10ms while others give me nearly 200ms.

fiction la..

I've heard of this as well, but I dismissed it, especially with the growing number of users which would be crowding any DHCP IP address.

I think only a static IP address would actually make a difference.

I see, thanks for sharing. For SG server, I highly recommend sg.gs (203.175.175.195). Usually, ping is around 9ms, lowest is 7ms, but during peak hour (~ 9PM) it will fluctate up to 20ms.

I have pinged sg.gs everyday using many different IP ranges for 2 months so far, the performance is more or less the same regardless of IP ..

Yeah, so far I would say it is probably fiction too... but I guess others might have different experience... who knows ?

Hmm... are you sure 117.x.x.x range is UniFi IP ?? According to online records, TM does not own any 117.x.x.x IPv4 addresses..

Here you can see the IPv4 address range that TM owns... bear in mind that TM doesn't allocate all of them for UniFi. For example, 1.9.x.x and 58.27.x.x range is mostly used for TM's CDN/cache service (eg. YouTube, Steam).

But if you really got 117.x.x.x range, then it would be quite interesting.

Agreed, static IP is still the best way for ISPs to shape traffic.

But I wonder if TM treats all their dynamic IP ranges equally... apart from the servers, I've also tried pinging the default gateway, and some are more stable than others (less jitter). But during peak hours, it is quite hard to tell sometimes, so it's still up for debate

I have not pinged each address, but I can fairly say that some IPs are not as congested as others - this is from my MMOs experience.

E.g., ESO (US server): I used to play on Sundays, and set my router to restart every Wednesday night. I can get 200-300ms, but on certain IPs, this is unstable and can reach 500ms or more. I'm blaming in on congestion, mainly. Thanks to it being unstable, especially at evening/night, I stopped playing western MMOs completely. Too bad I did not note which IPs were stable.

I see, thank you for sharing. For online games, sometimes it's hard to tell whether it's our connection, or the game server itself which is unstable... but if the server IP is public, then it's possible to test outside the game environment... but a lot of servers don't accept ICMP ping, sadly..

There is this website which allows users to ping any IP from servers around the world. I used to use it a lot, but not anymore, cause the results sometimes inconsistent...

But if you're curious, here's the results for 118.100.x.x range versus 175.142.x.x range. It is more or less same overall, but notice the big difference for some servers (eg. Nottingham, Frankfurt, Paris ).

Unfortunately, the website doesn't show the IPs of the servers, so it's not possible to double-check for 100% certainty. But feel free to experiment.

For reference, here is the results for sg.gs, almost every server < 200ms. TM's international routing still has a long ways to go

I just notice a difference today. Was trying to visit Christianity Today to read an article about Trump's Impeachment and the website took ages to load and times out. No issues on Maxis 4G on my phone. I had a 124 ip, reset the modem got 175. Same problem, reset again, got a 60 ip range and now it works perfectly. A few days ago I was having issues with royal jordanian's airlines website and now it works perfectly too.

I see, thanks for sharing. From personal experience using UniFi, if a website takes too long to load or won't load at all, it's most probably because of DNS or IPV6 (not IPV4) issue.

Nowadays more websites use both IPV4 and IPV6. By default, your device will try to resolve the domain (website link) using IPV6 first, if it can't connect, it will fall back to IPV4.

From own experience, the TP Link C1200 router has occasional issues with IPV6 connectivity, sometimes the browser won't load a website, or takes several seconds to load. To fix this I usually turn off/on IPV6 manually through the router, or reboot the router again.

If you want to experiment a bit, you can try disabling IPV6 in your router settings. You can also try using 1.1.1.1 or 8.8.8.8 for your router's DNS. Hope this helps

Heyy, thanks for the suggestions but I’m actually already using Google DNS. I’m also not using ipv6 as it makes my Netflix slow. I refrain from using cloudflare as it can affect the loading of my twitter media. I really do not think it’s a dns issue because when I run a trace route, the IP address comes up instantly. But the data goes to somewhere in Germany , gets stuck and starts timing out.

I can access Christianity today normally now, even without the 60 ip range. Maybe the route was very congested yesterday as only a few parts of the website managed to load.

One more website that I can’t for the life on me load on TM’s network is pornhubsurvey.com 😂. It’s just weird how some websites work and some don’t. I don’t even want to visit it , just want to know why it doesn’t work

Interesting, thanks for elaborating more info. Since you've already disabled ipv6 and using 8.8.8.8, it could very well be network congestion either at TM's side, or the website itself. Maybe next time when the website is slow to load, try using any VPN or proxy... if it still won't load, most likely it's the website/server-side issue ?

I noticed Cloudflare is sometimes quite unstable too, unlike Google. Few days back, Cloudflare's KL POP was down, I confirmed ping to 1.1.1.1 went up from 3ms to 80ms+ because they rerouted traffic to Hong Kong / Japan. Since many websites use Cloudflare platform nowadays, overall browsing experience felt very sluggish and slow for the whole day. Next day, Cloudflare rerouted to Singapore (8ms) until their KL POP was online again. You can check Cloudflare's worldwide POP status here.

Btw, TM blocks many websites (iinm at MCMC request), but you can get around it by using a different DNS. Since you're already using 8.8.8.8, it should work, if not, there might be some other issue.
