My daughter has just mentioned a weird issue she's noticed over the last
few months. The names of the device either Mac or iphone are updated
with an incremental number e.g. "Bob's iphone (1)" or "Macbook Air (1)".
This happens regularly and the phone is up to 401 and the Air up to 25.

it's seeing a duplicate on the network.
since there can't be two devices with the same name, it appends a
number to make it unique.
for some reason, the device is remaining visible rather than fully disconnecting.
does she have an old airport base station?

Ah, I see, her device names are too generic. The laptop is named
'Macbook Air' so that will be common.
Will get her to change the names.

This is on the University network and/or via Airdrop.
Thanks.

Actually in speaking to her, it's like the example above - 'Bob's
iphone'. Lots of her mates with more common names like, 'Alex's
iphone', don't have this issue.
Similarly, why has hers gone to 401? Surely, there can't be two 'Bob's
iphone (400)' to clash. Bob is not her name BTW.

As was already stated, network issues can cause this.

Like I said this is a University network - so she can't reboot her
router - and it isn't affecting other's with similarly named phones.

Anyone know why this is happening and how to stop it? I've never seen it
on my devices. It's more annoying than a problem, but it does mean
Airdrop contacts are never consistent.

This was a known Apple bug a while ago - I experienced it. Cannot for
life of me remember -exactly- what it was, and also this was -years-
ago. Something to do with mDNS Resolver I seem to recall. Involved an
awful lot of restarting everything in sight...
My guess is the network is having problems with UDP, as that was
definitely involved in the issue and resolution.

Ian's right - it was when Apple replaced mdnsresponder with discoveryd
in 10.10 for a couple of OS updates, and then reverted it.
https://arstechnica.com/gadgets/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-you-can-do-to-fix-it/
I remember 10.10's discoveryd DNS issues, but that is not the sole cause
of this issue. macOS 10.10 is a very old release, and as you said Apple
fixed those DNS issues with updates. I sure hope Ian's daughter isn't
running an unpatched version of an OS that no longer receives updates.
Also, Ian said this is happening with an iPhone as well, which wouldn't
be affected by a macOS bug. I've seen this issue on occasion for many
years, and the most common cause is a malfunctioning router. Typically restarting the router and affected devices fixes the problem.

She should probably report it to the uni's IT folks - do you have any references to router bugs that she could pass on?

Oops, my bad. : )

references to router bugs that she could pass on?
Nothing definitive, and it should be noted that it's plausible that it
could be related to a bug in Apple's networking stack as well as a
router networking issue. The root cause is unknown AFAIK, but it has to
do with the computer/device seeing the name in use on the network at the
time of connection. I've seen it happen when a Mac is configured to
use both Ethernet and WiFi at the same time, for instance. Some troubleshooting suggestions and ideas are in this AskDifferent thread:
<https://apple.stackexchange.com/questions/125411/how-do-i-stop-my-computer-name-from-automatically-and-incorrectly-changing>
Her IT department may be aware of others experiencing the issue, or not.
I'd definitely recommend having her make sure she is running a recent
version of macOS and iOS on her devices. I don't think I would spend too
much time on it though, as it's really just a cosmetic issue and doesn't prevent network connectivity.
