dhcp reservation (sometimes incorrectly called static dhcp), which is
supported by most routers.

leave your phone set to dhcp so that it will work when on other
networks, but when you're at your flat, you'll get the reserved dhcp ip
address.

That works /if/ your smartphone settings let you configure a static IP
address for the wifi connection. However, except for your own wifi
hotspots (wifi access point, wifi modem, wifi router), you don't get
control over the IP address of a gateway or router through which your
traffic passes. The owner of the wifi hotspot dictates how they
configure their NAT-capable device. You may define a static IP address
for your phone, but Internet hosts will see the access point's IP
address.

Also, if the static IP address you choose is not within the allowed
range by the upstream wifi device, like your wifi router only allows one
range, but you pick an IP address outside that range, then you won't get
a wifi connection. If it is not your wifi hotspot, you won't know what
IP range is allowed in the config of the upstream wifi device.

If you're asking how to get a static IP address for cellular-based
Internet connections, you'll have to ask your cellular provider if they
provide that service, and if it is free or paid. Every time your UE
(User Equipment aka "mobile phone" is [re]started, or when moving across
invisible zones that you are unaware, the IP address of your phone
changes.

Whether you can get a static IP address depends on which carrier you
use. Some do, some don't. My guess is most don't. Those that do will
likely charge you for that value-add service.

Give your phone(s) a static ip address in your router. How that's achieved
differs in each router's config. Check the manual.

I know how to deal with ip local addresses, I don't have a flat,
and that posting was NOT from me. So either it's glitch at aioe
or a falsification.

That would have the router fix the IP address for the phone based on the
phone's MAC address; else, how could the router identify which device
was connected to it to then have its DHCP server always assign the same
IP address to that device? Plus, that only works when the phone is
connecting to the router via Ethernet cable or via wi-fi, not when the
phone is connecting to the cellular carrier which isn't touching the
router. So far, we don't know for which connection PietB wants a static
IP address: cellular or wifi.

that is a very bad idea.

the correct solution is to use dhcp reservation, which will work as
desired locally and have no effect on other networks.

that's true for all settings on all routers, plus a few of them do not
offer dhcp reservation or may have a different name.

static ip addresses and dhcp are different things.

phones do not use an ethernet cable except in highly unusual
circumstances, but even then, the same issue applies.

yes 'we' do.

Only the router is assigning local ip addresses and they can be static.
Public addresses are always managed by the networks. A phone is just a
client in these networks.

I suspect it's a matter of terminology ...

I would call it static if you assigned an IP to the phone in the PHONE's own
settings

I would call it a reservation if you assigned an IP for the phone in the
ROUTER's settings

it can be static, but as i said, that's a *very* bad idea.

yep, which is why dhcp reservation on his router at his flat is the
proper solution. it will have *no* effect on public networks. only his
own.

those are the correct definitions.

using a static ip will cause all sorts of problems when the phone
connects to another network. it's a really bad idea, and not just for
phones either.

using dhcp reservation only affects the user's own network. other
networks will be unaffected since there is no reservation there.

Yes I would always choose address reservation (configured at the router)
over static address (configured at the computer/phone) for this very reason:
that your phone gets a fixed address from your own network but still gets an
address in the same subnet or a different subnet when it connects to another
router. For a computer which never leaves the house, it doesn't matter, but
for a portable device like a phone, tablet or laptop you *must not* give
your phone a static address of (for example) 192.168.1.20 if either a) there
may be another computer that the away-from-home router has already given
that address, or b) the router is configured to use another subnet such as
192.168.2.x. In the first case you will get an IP address conflict; in the
second case the router probably won't talk to your device (or at least won't
route any external traffic to/from your device).

a very clear description.

> For a computer which never leaves the house, it doesn't matter,

normally yes. although static ip addresses are still a hassle to manage.

some devices do need to have a static ip, such as a dns server, which
does not move between different networks (and most people don't have
their own anyway).

I just looked at my phone and my router which confirms what Andy said.

I have not tried on Android, but the setup should know to use a fixed IP
on certain WiFi setup, and dhcp on the rest. I do that on some laptops.

Sometimes it is not practical this method. For instance, there is a
limited number of assignations on home routers. On others, the router is
restored to factory or tampered remotely by the ISP. Otherwise, yes, it
is the best method.

Why isn't anyone mentioning what I noticed in my phone which is that the
"static" address is _per_ access point SSID.
<https://i.postimg.cc/nchSVcmS/vysor30.jpg> Static/Reserved IP address

Notice that you can set any other access point to be any other way you
want, so I think it's perhaps probably wrong what people are saying.

Given it seems that it's a static address _per SSID_, the ONLY way that
could cause a problem is if you connect to the same SSID - but - we would
"hope" that it's not necessarily the SSID but the unique MAC address of
that SSID (although the Android GUI doesn't say that it's the BSSID).

In summary, looking at my phone (which has been set up this way for ages
without problems), I don't think people are necessarily correct when they
assume the _phone_ has the static address... as it appears on my Android 11
phone that it's a specific _SSID_ that gets that static address...

.... and it "may" even be set to only a specific BSSID for all we know.

As Carlos says, it's _per SSID_ on my phone (maybe even per BSSID?)

I do both but I agree that I "probably" shouldn't do that (but I do).

What's the worst thing that can happen if I do both? Dunno. Do you?

Though beware that recent android (probably iThings too) can present a
randomised MAC address, instead of the device's physical MAC address, this is to
prevent you being tracked by e.g free instore wifi, but you can tell each SSID
saved to your phone to not use randomisation, so that DHCP reservations work
properly.

Thanks Andy for taking a look at the images and for bringing up the
randomization of the MAC address, which, for my Android 12, is the default.

I _love_ working alongside you (as opposed to the iKooks) since you try to
add value in each post, much like I do... (instead of defending everything
that any one company happens to do) so that everyone benefits from the
added value you and I continually add to the permanent record on this ng.

I just checked and the MAC address that the router "thinks" is the MAC
address of the phone _is_ what the phone itself randomized that MAC address
to at the time that the network connection was originally set up to the
router SSID.
<https://i.postimg.cc/k4K8dZqv/vysor31.jpg> Random MAC address is static

Somewhere I remember reading that you can't (easily?) change the randomized
MAC address per SSID once it has been established. Dunno if that's true.

I just checked other SSIDs on the phone (I have plenty) and some are the
same randomized MAC address but others are a _different_ randomized MAC
address. Dunno exactly how that happened as I didn't touch anything (I left
the randomization of the MAC address on the phone at the Android 11
default.)

BTW, what's a good privacy-aware DNS set of servers? I'm using Google,
which again, I don't remember setting up but maybe I did that to myself.

If it's a randomized address...

....why did you need to redact it? What could anyone possibly hope to
learn about your device from random 48-bit number?

Ditto blocking the private IP address?

Here:

My current IP address is 10.0.69.51. Go ahead and hack my computer!

You're concerned about privacy and you're using a Google server...

....of any kind?

Google's whole business model is mining your personal data.

that's optional, useful in some situations and not in others.
