the old UK reverse name notation actually comes from some sensible
ideas - firstly from the big-endian processing methods - but also the
most important part of the address
comes first - ideal for global routing decisions early. who cares
about the actual hostname , get to the actual TLD ;-)
have seen and suffered from same. nearby strikes can cause enough
surge to fry things. best solution - air-gaps where possible between
devices (eg fibre to link switches), surge protectors on ethernet
cables where needed (eg feeds from Access points) - and if the APs
have external antennae
do you have any of the WLC settings on such as dynamic power
assignment (which allows the controller to work out neighbour cell
and reduce the signal to stop much overlap). which 5GHz channels are
being used - if you're using those in DFS space then RADAR detection
means that DAC
use Direct Access PAC file for clients to get the right endpoints.
Apply QoS to that traffic - and use that same PAC file to feed the IP
ranges into your QoS
rules on the firewall/router ?

another prediction would be that your internet connection (and most devices
in house) connected by 5G - maybe with some local
WiFi - 802.11ax - if theres still spectrum left after the LTE groups have
taken it all for aforementioned 5G purposes...
legacy devices, still around for another
as already said - this can be covered with adequate processes and
management (even so far as, not doing your job right? time
for HR...). however, there are many ways to ensure that random ports arent
doing anything other than what they should be doing - most of these
are L2 security features -

+1 for the APC kit :)
yet another ZTE issue . :(
thats probably a key part of the experiment - to find locations and
systems where 18.104.22.168 is trashed.
it should be routable and its about time that vendors stopped messing
around in that space - hopefully this is
one of the sticks that prods people to start to behave - at which
intercept/inject? why. an ISP can just run its own standard DNS
servers on 22.214.171.124 and 126.96.36.199 and point
their customers to those - they own their routing space, they can just
route to those locallyso anyone thinking they
can avoid their ISP by choosing some other addresses are
Scout Aircheck G2 is quite nifty - but a lot of tools out there are
only just a little bit above what you can do with a decent Android
phone (one with 802.11a/b/g/n/ac chipset) and
WiFiAnalyzer ! :)
if you're already slurping the commercial koolaid (support contracts,
someone to blame etc etc) - then Aruba Clearpass?
(otherwise local homebrew with FreeRADIUS core or PacketFence as
FOSSOTS ;-) )
Commercial, or free? For commercial route explorer should do the job, for
free, run eg quagga or such with relevant actions on logs.
i'm sure theres plenty of aerial in europe. usually carried on e.g.
the top messenger cable on pylons - given i've attended talks about
the issues of fixing such fibre after storms in Scotland :)

As per other statements of such seen elsewhere online, do you have examples or

+1 for Statseeker. Ease of use etc (price depends on eg site size etc). Can do
lots on just one mid server unlike some other bloaty solutions out there. But
we also still use MRTG for some local bespoke measurements

Um. You don't have an option for old copper plants. This stuff gives you

If you can do 10g you really shouldn't be carrying about this stuff. In the
optical world just jump to using 10Gig (where you can)

Yes but this was an announcement about freerouter. If RouterOS has an

The host has to support it... I've only seen the cisco anyconnect client add
such support to the host
I'm surprised that noone of the home wifi router folk haven't cornered the
market on that one in terms of client separation. Most people don't need the
devices to talk to each other so by default all ports on different VLANs ..

No. CentOS follows RedHat. They backport fixes to older versions rather than
put the new version out. It appears that have aversion to new feature and just
want to put the fixes onto the older versions. So that 9.9.4 probably has 60%
of the changes that the diff of 9.9.4 has to 9.9.8 . This

'QoS problems are to be expected' . Uh?
Don't you put QoS into place just to ensure that the minimum bandwidth you need
to ensure critical services (such that your voice traffic is not impeded for
example) are NOT affected across your WAN links when there are big globs of
data banging around?

No. They should just ask, with the best geek intonation, whether this

I'm sure they'd gladly report that their Internet is 24 mbit and not just 32

'We plan to use DHCPv6 rather than SLAAC for a variety of reasons'
