Thanks for taking time Jay & Marc!!
Here is the information:
Netstat print showing listening on 80:
[root@localhost ~]#
[root@localhost ~]# netstat -nap | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
5268/httpd
However while I tried telnetting in local host itself, I can see two
different printouts:
[root@localhost ~]# telnet localhost 80 --refusing here
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Nmap from the localhost looks like:
[root@localhost ~]# nmap localhost
Starting Nmap 6.40 ( http://nmap.org ) at 2016-09-14 21:45 IST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.0000050s latency).
Other addresses for localhost (not scanned): 127.0.0.1

PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
80/tcp open http

[root@localhost ~]#
Whereas from the neighboring server in same subnet it looks like (No port
80)
[root@TEST_ZABBIX_1 ~]# nmap 10.xx.xx.xx
