Superior ping

For those who want to try it at home:

 undefined

    
ping 33333333
ping 55555555

I am sorry, two random Internet users in Korea and Germany, your IP addresses are simply special.

Obligatory: Fuck Drake.
There are dozens of meme templates like this that you could have used instead
- Jesus. If you see a kid with a balloon, do you have a burning need to tell them that there was probably exploitation involved in the harvesting of the rubber?
  
  Epic false equivalence.
  
  Imagine defending Drake, disgusting.

ping 9.9.9.9
It's 1111 higher.

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.
- 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
  
  Voodoo! I had no idea.
  
  Can you explain how/why its the same?
  My instinct says its actually trying to reach 127.1.0.0 (which is still local host), but that's an educated guess at best.
  Edit: Question was answered later on thread

Ping ::1

ping 1.1 also works. It resolves to 1.0.0.1, which is Cloudflare's secondary DNS
- It sure is better then ping 194.204.152.34 which I used to use.
  
  Prior to cloud flare and Google doing DNS, a common one was 4.2.2.2 which is a level 3 IP.
- Wow, thank you!
- Oh shit. Didn't know this either. Kind of like ipv6 in a way
  
  IPv4 has some other features too.
  undefined
  
  $ ping 0x8.02004010
  That'll be Google's root DNS server, using hexadecimal and octal representations.

I prefer:
undefined

ping 133742069
(probably lands you on a list tho...it's a US DoD IP)
- Gotta make sure to do it from a Russian VPN too.
- ~~[https://iplocation.io/ip-whois-lookup/133.74.20.69](Looks like the Japanese Aerospace Agency) unless ~~I'm completely misunderstanding how entering a string of numbers without periods works in a ping
  
  Ah yeah there's a little misunderstanding. IP addresses can be represented as 32-bit unsigned integer numbers, where each 8-bit chunk is separated by a dot.
  So the conversion is: 133742069 (decimal) -> 00000111111110001011110111110101 (binary) -> 00000111.11111000.10111101.11110101 (8-bit chunks) -> 7.248.189.245 (resulting IP)

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

- 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 g.co to test ipv6

55555555
All addresses that that start in 555 were left open by the internet protocol developers just for movies and TV shows.
- I don't get it, the first octet (?) max is 256.
  
  Yes, but you can write it in different ways. If the numeric string contains a dot, left of it must be between 0 and 255, and is put in the highest byte of the address. If the rest also contains a dot, repeat, but put it into the second highest byte.
  BUT: if the string does not contain a dot, the number is put into the remaining bytes.
  So 123.256 is a valid address. The 123 goes into the top byte, the 256 goes into the remaining three bytes, so the address would be 123.0.1.0.
  Most common example is 127.1, which is short for 127.0.0.1 - the localhost address.
  
  Yes, in octal notation. You can express an IP using other bases.
  
  255
  Small correction, but an important one: 0 is a number too.
  In terms of IP masking and broadcast addresses, the max is 255.255.255.255

Or, if you're me,

 undefined

Okay, I'm learning networking but have no idea what this means

  interesting . . In my head, I think of ip addresses like just decimal values or integers separated by periods, but clearly a decimal value isn't processed as such by a computer. To think that IP addresses are simply strings is pretty interesting to my amateur mind, because for all my life I thought of them as technical computer jargon that isn't the same as what I used to think strings were: words!
