Hi All,
Is there some special meaning (like 127.0.0.1.) to
the following IP address?
224.0.0.251
Many thanks,

It is an IP Multicast address.
host 224.0.0.251
will tell you a bit more.
Alan.
Hi Alan,
$ host 224.0.0.251
Host 251.0.0.224.in-addr.arpa. not found: 3(NXDOMAIN)
Not sure what I am suppose to find.
This is why I ask (VLC's doing):
kernel: Vlan-out Everything Else IN= OUT=eth0.5 SRC=192.168.254.10
DST=224.0.0.251 LEN=56 TOS=0x00 PREC=0x00 TTL=255 ID=0 DF PROTO=UDP
SPT=5353
DPT=5353 LEN=36
eth0.5 is a virtual Ethernet too, not hooked to the Internet.
And port 3535 UDP?
$ grep -i 3535 /etc/services
ms-la 3535/tcp # MS-LA
ms-la 3535/udp # MS-LA
Thank you for the help,
-T
Lysdexic are we? It's 5353 which seems to be an alternate DNS address.

Hi Joanne,
$ grep -i 5353 /etc/services
mdns 5353/tcp # Multicast DNS
mdns 5353/udp # Multicast DNS
Makes more sense.
Interesting. M$'s list of official ports does not
list it:

I have been working on a PCI (credit card security) probe
of a customer's site all day. I keep mixing up my ports
with their's. (When you probe the entire network, you get your own
IP as well as their's and everyone else on the network.)
AAAAAAHHHHHHHH!!!!
Apparently "lysdexic" is catching. Now the point I really
wanted to make was, was, was... Oh phooey, I forgot. :')
Who are you again? Are you still in the Navy? :-D
