"arpatxt" takes a file in "HOSTS.TXT" format, much as you would
receive from running "/etc/gettable sri-nic.ARPA" on an Internet host. 
It is NOT a file with the same format as /etc/hosts.  

Here's the start of HOSTS.TXT which describes its format:

; DoD Internet Host Table
;  8-Oct-87
;  Version number 679
;
; Changes, corrections, comments or questions to (HOSTMASTER@SRI-NIC.ARPA)
;
; The format of this file is documented in RFC 952, "DoD Internet
; Host Table Specification", which is available online at SRI-NIC
; as the file
;              [SRI-NIC]<RFC>RFC952.TXT
;
; It may be retrieved via FTP using username ANONYMOUS with
; any password.
;
; The format for entries is:
;
; NET : NET-ADDR : NETNAME :
; GATEWAY : ADDR, ADDR : NAME : CPUTYPE : OPSYS : PROTOCOLS :
; HOST : ADDR, ALTERNATE-ADDR (if any): HOSTNAME,NICKNAME : CPUTYPE :
;   OPSYS : PROTOCOLS :
;
; Where:
;;  ADDR = internet address in decimal, e.g., 26.0.0.73
;;  CPUTYPE = machine type (PDP-11/70, VAX-11/780, FOONLY-F3, C/30, etc.)
;;  OPSYS = operating system (UNIX, TOPS20, TENEX, ITS, etc.)
;;  PROTOCOLS = transport/service (TCP/TELNET,TCP/FTP, etc.)
;;  : (colon) = field delimiter
;;  :: (2 colons) = null field
