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?
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
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
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.
Voodoo! I had no idea.
It's all in the documentation. But people don't read anymore.
Ping ::1
ping g.co to test ipv6
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
That'll be Google's root DNS server, using hexadecimal and octal representations.
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.
~~[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)
Thank you!!
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;")
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
Oof of course. 256 entries from 0 - 255.
It's been a long long time since my ccent

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!
I don't want to go so far as to tell you how to think, but as long as we are talking about how to visualize IP addresses, you may want to check out subnets and subnet masking.
The notation of IP addresses starts to make sense when you think about the early days of TCP/IP when all IP addresses were public and NAT'ing wasn't really required yet. Basically, there needed to be ways for networks to filter traffic by IP blocks that were applicable. (It was [in part] a precursor to collision avoidance, but absolutely not the full story.) We still use addressing and masking today, but it's more obvious when it's local. (Like in data centers, where it's super practical to mask off a block of addresses for a row or rack of servers.)
To your point, yeah. IP addresses are probably more comparable to the Dewey Decimal System rather than actual numbers and thinking of them as strings is probably easier.
Oh no worries, I am writing a Cisco networking exam in about a month, so I've actually studied subnets and addressing a good amount, but I don't mind the refresher!
I was just speaking more generally, in terms of programming, where integers and strings are different data types, yet you can store numbers as a string, which I always found interesting.
