Need help with Korn Shell script for substring printing

Hi all,
I am new to scripting.

I have a file with colon separated values called mylist.txt

Code:
cat mylist.txt
192.123.76.89:lmprod89
162.122.20.28:lmtstserver28
10.80.32.139:hewprod139

.
.


using our internal os utility (called mvsping) we need to check all these servers if they are reachable


Our field 1 is IP and field2 is servername. I need the output of the script's to show a message like

Server : $servername "with IP "$ipaddress"is pingable"

I know how to write the IF condition part here by checking the exit status. But i need some help in looping through each lines getting field1 and printing servername(which is field2) like above if the exit statu is 0


Using korn shell, i need to write this script . Will this require a loop inside a loop ?


Code:
for iplist in `cat mylist.txt | cut -d: -f1`
do
  if
  #i will do my logic using vsping in IF condition here
  #it will be something like
  # vsping ip . if exit status = 0 , then pingable
  
  
  
  
  fi

done
