What reasons are there for the following returning the IP address
instead of the hostname?
gethostbyaddr($_SERVER)

Hello all,
the documentation for the socket module says that gethostbyaddr should
return the primary host name and alternative host names if there are
any. But the alias list is empty even in cases where I know aliases
exist. I can get them using gethostbyname_ex, but that only works with
names, not with IP addresses, and I want to resolve both sorts.
I'm using Python 2.3.2 on Windows NT4, SP6.

Hello:
I am using gcc on RedHat Linux 9.
When I try to do a reverse dns query using gethostbyaddr, it works
fine for hosts that have a PTR record, but it returns null for hosts
that have a CNAME record. Any ideas how to work around this?
Here is an example:
dig -x 66.54.79.4

Hi,
I have a SunOS TCP/IP client program worked fine for a long time
until yesterday.
Now, my TCP/IP server program is located on different
DNS server.
The gethostbyaddr ( ) is now returned NULL instead.

I have a list of IP addresses I am testing with socket.gethostbyaddr().
For the most part, I am able to get a hostname returned to me when I
run gethostbyaddr(). I am also hoping this will allow me to tell if a
computer is up or down. However, in my environment, I am finding that I
am able to get a hostname even though I am unable to actually ping that
server (when I ping a server i like this, I get 'request timed out'
messages telling me...

Hi
Since yesterday about 11.00 CET the gethostbyaddr function doesn't seem
to be working. All I get is the IP address back. Is this something
general to all PHP users or is this specific to my server?
Thanks
BTW what's the difference between comp.lang.php, alt.php and
alt.comp.lang.php, shouldn't these groups be merged?

Hi,
I am facing a peculiar problem. socket.gethostbyaddr is not working
fine on my MAC for ip addresses on the LAN. The LAN happens to consist
of linux and windows machines and this is the only one MAC on the
LAN.
Please see the example below. I am getting error: socket.herror: (1,
'Unknown host')

hi,
I came to know that gethostbyaddr is deprecated in Visual Studio 2005 by the introduction of getnameinfo function.
Can i know the reason for the deprecation of gethostbyaddr function.
Is there any security issues related with this function?
Also came to know that calling this function is not thread safe.
I am not able to get the exact reason for not using gethostbyaddr function.

When there is no rDNS record on an IP address, then it might take a while for
the reverse lookup to timeout. I'm thinking of how on a tracert you can
observe the delay.
If so, then calling gethostbyaddr() can delay the serving of the web page,
right? Because gethostbyaddr() is not forked into a separate process. So I
suppose I'd need to call gethostbyaddr() as the very last task for a script.
Does that sound right? Or is there another...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
