Superior ping

Best ping is 127.0.0.1
It always resolves!
- 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...
  
  Voodoo! I had no idea.
  
  even shorter: ping 0
  
  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
- 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.
  
  What about 127.255.255.255 ?

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.
  
  $ ping 0x8.02004010 PING 0x8.02004010 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=22.8 ms
  That'll be Google's root DNS server, using hexadecimal and octal representations.

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;")

I prefer:

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.
  
  "one ping only, please"
- 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...
- ~~[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)

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?
- 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.
  
  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
  
  Yes, in octal notation. You can express an IP using other bases.

Or, if you're me,

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
- 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.
- 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.

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!
- It's simple. Picture a series of tubes...

ping g.co to test ipv6

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?
  
  I block any and all IPs that resolve outside my postal code. Support local phishing.
