MODERATORS
I'm probably going to get downvoted to hell but I have to ask: Can someone please explain? I'm perpetually trying to expand my knowledge on the technical side of Linux.
This is the behaviour of inet_aton, which ping uses to translate ASCII representations of IPv4 addresses to a 32 bit number. Its manpage: https://man7.org/linux/man-pages/man3/inet_aton.3.html
It recognizes the usual quad decimal notation of course, but also addresses of the form a.b.c or a.b, or in this instance, a, with is taken to be a 32bit number.
Each part can also be written in hex or octal, with the right prefix, such that 10.012.0x800a is as valid form for 10.10.128.10.
Not all software use inet _aton to translate ASCII addresses. inet_pton for instance (which understands both v4 and v6) doesn't
An IP address is a 32-bit number, usually expressed as four 8-bit numbers separated by dots. Converting 33333333 to hex we get 01FCA055; splitting that into pairs and converting back to decimal gives 1, 252, 160, 85.
Typically an IP address is represented as 4 8-bit integers (1.252.160.85), but it can also be represented as a single 32-bit integer (33333333). The ping utility accepts both forms.
Also two random internet users in Korea and Germany, your IP addresses are blocked by mail server since I started getting phishing emails from your country.
Yo7 block entore countries over a few fishing e-Mails?
Best ping is 127.0.0.1
It always resolves!
Fun fact 127.0.0.1-127.255.255.254 is all localhost
Pretty insane that around 0.4% of all IPv4 addresses are wasted.
Wayyyyyy more than that is wasted.
Apple (and others) used to have an A class. I think they gave some of it back to the pool.
public universities have entered the chat
A few years ago my old university finally went with NAT instead of handing out public IPs to all servers, workstations and random wifi clients. (Yes, you got a public IP on the wifi. Behind a firewall, but still public.) I think they have a /16 and a few extra /24s in total.
Honestly there isn't much reason to go with NAT unless you are looking to lease/sell IPs
The sad part is that almost no universities do IPv6
Try pinging 127.1 - it is the same, but shorter.
Just another tipp from someone who learned TCP/IP from reading the sources over three decades ago...
even shorter: ping 0
This is a special case. This resolves to 0.0.0.0, and technically cannot be routed. Some(!) systems use it as a kind of alias for all local network addresses, but it is not a given.
I'm aware. Conveniently this works on all the systems I've tried, making it useful for testing local services (e.g. ssh 0).
That resolves to 0.0.0.0 - rarely useful
But itβs shorter!
But it does not work by definition, it is non-routable. That some systems use it as an alias is a different issue.

ping 1.1 also works. It resolves to 1.0.0.1, which is Cloudflare's secondary DNS

ping 9.9.9.9
It's 1111 higher.
I prefer:
ping 133742069
(probably lands you on a list tho...it's a US DoD IP)
I fondly remember regularly logging into simtel20.wsmr.army.mil back in the days (WSMR=White Sands Missile Range). No issue, just used "anonymous" as the username, and your email address as the password. And even the email address was just a convenience...
Gotta make sure to do it from a Russian VPN too.

For those who are still confused, ping works with 32 bit unsigned integers. While there certainly are more uses, it's a much more convenient method for storing IP address in a database as it's easier to sort and index than 4 numbers separated by 4 periods
http://www.aboutmyip.com/AboutMyXApp/IP2Integer.jsp?ipAddress=1.1.1.1
it's so simple!
ping -c 4 $(mysql -u frodo -p keepyoursecrets -D /home/pingtargets.db -se "SELECT ip FROM servers ORDER BY RAND() LIMIT 1;")
Ping ::1
55555555
All addresses that that start in 555 were left open by the internet protocol developers just for movies and TV shows.
And the ones starting with 800 are for Pay Per View?

Obligatory: Fuck Drake.
There are dozens of meme templates like this that you could have used instead
There are things you could have done besides act self righteous on the internet, and yet here you are
It takes 0 effort to not support a creep
Ah you see the mistake you've made is thinking that somehow posting a picture of someone supports them. This is because you spend too much time looking at screens
It makes them part of the cultural Zeitgeist. And when they are already famous, it maintains their currency in that regard.
Yes this is an example of internet think
