Hello! I'm trying to ping some lemmy instances to understand which one is the faster, so I'm just using the ping command:

$ ping lemmy.ml
PING lemmy.ml (54.36.178.108) 56(84) bytes of data.
64 bytes from lemmy.ml (54.36.178.108): icmp_seq=1 ttl=49 time=24.4 ms

ping lemmy.world
PING lemmy.world (135.181.143.230) 56(84) bytes of data.
64 bytes from static.230.143.181.135.clients.your-server.de (135.181.143.230): icmp_seq=1 ttl=52 time=58.2 ms

but if I try with certain instances:

ping vlemmy.net
PING vlemmy.net (109.78.160.70) 56(84) bytes of data.

it just hangs there, forever. if I try to ctrl+C it, it displays

^C
***
vlemmy.net ping statistics
***
13 packets transmitted, 0 received, 100% packet loss, time 12267ms

why does this happens? I can perfectly visit vlemmy.net from my browser so I really can't understand whay is this happening

One possibility is that the server is configured not to respond to pings

what advantages can derive from this?

Prevents some types of port scanning normally. Don't know about other advantages

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
