Try something like:
Code:
awk 'BEGIN {
        p[0] = "DD"
        p[1] = "AA"
        p[2] = "BB"
        p[3] = "CC"
}
{       printf("%s %s\n", p[NR % 4], $0)}' input

As always, if you are using a Solaris/SunOS system, use /usr/xpg4/bin/awk or nawk instead of awk.

net::dhcp::constants

Net::DHCP::Constants(3pm)				User Contributed Perl Documentation				 Net::DHCP::Constants(3pm)

NAME

       Net::DHCP::Constants - Constants for DHCP codes and options

SYNOPSIS

	 use Net::DHCP::Constants;
	 print "DHCP option SUBNET_MASK is ", DHO_SUBNET_MASK();

DESCRIPTION

       Represents constants used in DHCP protocol, defined in RFC 1533, RFC 2132, RFC 2241, RFC 2485, RFC 2563, RFC 2937, RFC 3004, RFC 3011, RFC
       3046.

TAGS

       As mentioned above, constants can either be imported individually or in sets grouped by tag names. The tag names are:

       o   bootp_codes

	   Imports all of the basic BOOTP constants.(01) BOOTREQUEST(02) BOOTREPLY

       o   htype_codes

	   Imports all HTYPE (hardware address type) codes.(01) HTYPE_ETHER(06) HTYPE_IEEE802(08) HTYPE_FDDI

	   Most common value is HTYPE_ETHER for "Ethernet".

       o   dhcp_message

	   Import all DHCP Message codes.

	   (rfc2132)

	     (01) DHCPDISCOVER(02) DHCPOFFER(03) DHCPREQUEST(04) DHCPDECLINE(05) DHCPACK(06) DHCPNAK(07) DHCPRELEASE(08) DHCPINFORM(09) DHCPFORCERENEW

	   (rfc4388)

	     (10) DHCPLEASEQUERY(11) DHCPLEASEUNASSIGNED(12) DHCPLEASEUNKNOWN(13) DHCPLEASEACTIVE

	   Nb. Previously Cisco used 13 for DHCPLEASEQUERY. If you need to decode or encode packets to communicate with such a system, you might
	   simply us the integer rather than the constant - or use the updated constant and comment in your code appropriately.

       o   dho_codes

	   Import all DHCP option codes.(000) DHO_PAD(001) DHO_SUBNET_MASK(002) DHO_TIME_OFFSET(003) DHO_ROUTERS(004) DHO_TIME_SERVERS(005) DHO_NAME_SERVERS(006) DHO_DOMAIN_NAME_SERVERS(007) DHO_LOG_SERVERS(008) DHO_COOKIE_SERVERS(009) DHO_LPR_SERVERS(010) DHO_IMPRESS_SERVERS(011) DHO_RESOURCE_LOCATION_SERVERS(012) DHO_HOST_NAME(013) DHO_BOOT_SIZE(014) DHO_MERIT_DUMP(015) DHO_DOMAIN_NAME(016) DHO_SWAP_SERVER(017) DHO_ROOT_PATH(018) DHO_EXTENSIONS_PATH(019) DHO_IP_FORWARDING(020) DHO_NON_LOCAL_SOURCE_ROUTING(021) DHO_POLICY_FILTER(022) DHO_MAX_DGRAM_REASSEMBLY(023) DHO_DEFAULT_IP_TTL(024) DHO_PATH_MTU_AGING_TIMEOUT(025) DHO_PATH_MTU_PLATEAU_TABLE(026) DHO_INTERFACE_MTU(027) DHO_ALL_SUBNETS_LOCAL(028) DHO_BROADCAST_ADDRESS(029) DHO_PERFORM_MASK_DISCOVERY(030) DHO_MASK_SUPPLIER(031) DHO_ROUTER_DISCOVERY(032) DHO_ROUTER_SOLICITATION_ADDRESS(033) DHO_STATIC_ROUTES(034) DHO_TRAILER_ENCAPSULATION(035) DHO_ARP_CACHE_TIMEOUT(036) DHO_IEEE802_3_ENCAPSULATION(037) DHO_DEFAULT_TCP_TTL(038) DHO_TCP_KEEPALIVE_INTERVAL(039) DHO_TCP_KEEPALIVE_GARBAGE(040) DHO_NIS_DOMAIN(041) DHO_NIS_SERVERS(042) DHO_NTP_SERVERS(043) DHO_VENDOR_ENCAPSULATED_OPTIONS(044) DHO_NETBIOS_NAME_SERVERS(045) DHO_NETBIOS_DD_SERVER(046) DHO_NETBIOS_NODE_TYPE(047) DHO_NETBIOS_SCOPE(048) DHO_FONT_SERVERS(049) DHO_X_DISPLAY_MANAGER(050) DHO_DHCP_REQUESTED_ADDRESS(051) DHO_DHCP_LEASE_TIME(052) DHO_DHCP_OPTION_OVERLOAD(053) DHO_DHCP_MESSAGE_TYPE(054) DHO_DHCP_SERVER_IDENTIFIER(055) DHO_DHCP_PARAMETER_REQUEST_LIST(056) DHO_DHCP_MESSAGE(057) DHO_DHCP_MAX_MESSAGE_SIZE(058) DHO_DHCP_RENEWAL_TIME(059) DHO_DHCP_REBINDING_TIME(060) DHO_VENDOR_CLASS_IDENTIFIER(061) DHO_DHCP_CLIENT_IDENTIFIER(062) DHO_NWIP_DOMAIN_NAME(063) DHO_NWIP_SUBOPTIONS(064) DHO_NISV3_DOMAIN(065) DHO_NISV3_SERVER(066) DHO_TFTP_SERVER(067) DHO_BOOTFILE(068) DHO_MOBILE_IP_HOME_AGENT(069) DHO_SMTP_SERVER(070) DHO_POP3_SERVER(071) DHO_NNTP_SERVER(072) DHO_WWW_SERVER(073) DHO_FINGER_SERVER(074) DHO_IRC_SERVER(075) DHO_STREETTALK_SERVER(076) DHO_STDA_SERVER(077) DHO_USER_CLASS(078) DHO_DIRECTORY_AGENT(079) DHO_SERVICE_SCOPE(080) DHO_RAPID_COMMIT(081) DHO_FQDN(082) DHO_DHCP_AGENT_OPTIONS(083) DHO_ISNS(085) DHO_NDS_SERVERS(086) DHO_NDS_TREE_NAME(087) DHO_NDS_CONTEXT(088) DHO_BCMCS_CONTROLLER_DOMAIN_NAME_LIST(089) DHO_BCMCS_CONTROLLER_IPV4_ADDRESS(090) DHO_AUTHENTICATION(091) DHO_CLIENT_LAST_TRANSACTION_TIME(092) DHO_ASSOCIATED_IP(093) DHO_CLIENT_SYSTEM(094) DHO_CLIENT_NDI(095) DHO_LDAP(097) DHO_UUID_GUID(098) DHO_USER_AUTHENTICATION_PROTOCOL(099) DHO_GEOCONF_CIVIC(100) DHO_PCODE(101) DHO_TCODE(112) DHO_NETINFO_ADDRESS(113) DHO_NETINFO_TAG(114) DHO_URL(116) DHO_AUTO_CONFIGURE(117) DHO_NAME_SERVICE_SEARCH(118) DHO_SUBNET_SELECTION(119) DHO_DOMAIN_SEARCH(120) DHO_SIP_SERVERS(121) DHO_CLASSLESS_STATIC_ROUTE(122) DHO_CCC(123) DHO_GEOCONF(124) DHO_VI_VENDOR_CLASS(125) DHO_VI_VENDOR_SPECIFIC_INFOMATION(128) DHO_ETHERBOOT_SIGNATURE(129) DHO_CALL_SERVER_ADDRESS(130) DHO_DISCRIMINATION_STRING(131) DHO_REMOTE_STATISTICS_SERVER(132) DHO_VLAN_ID(133) DHO_L2_PRIORITY(134) DHO_DSCP(135) DHO_HTTP_PROXY_FORPHONES(136) DHO_OPTION_PANA_AGENT(137) DHO_OPTION_PANA_V4_LOST(138) DHO_OPTION_CAPWAP_AC_V4(139) DHO_OPTION_IPV4_ADDRESS_MOS(140) DHO_OPTION_IPV4_FQDN_MOS(141) DHO_SIP_UA_CONFIGURATION_SERVICE_DOMAINS(150) DHO_ETHERBOOT(176) DHO_IP_TELEPHONE(177) DHO_PACKETCABLE_DEPRECATED(208) DHO_PXELINUX_MAGIC(209) DHO_CONFIGURATION_FILE(210) DHO_PATH_PREFIX(211) DHO_REBOOT_TIME(212) DHO_OPTION_6RD(213) DHO_OPTION_V4_ACCESS_DOMAIN(220) DHO_SUBNET_ALLOCATION(221) DHO_VIRTUAL_SUBNET(255) DHO_END
