confused by netstat result












0















I ssh to my ubuntu server and run sudo netstat -a -p and I get this:



tcp        0      0 ip-172-31-25-123.us:ssh mailDOTjjtoursDOTcom:54531  ESTABLISHED 1516/sshd: ubuntu [


And when I use my other ssh client, it shows another jjtoursDOTcom in there.



I use putty and bitvise.



Why does it show that domain name?
(I replaced dots . with DOT in domain names)

          netstat does a reverse DNS lookup to display a hostname instead of an IP. You can disable reverse DNS lookup with the -n option.



          Try this:



          $ sudo netstat -anp
