For the purpose ofproviding services to unknown callers, a service contact port isdefined. This list specifies the port used by the server process as itscontact port. The contact port is sometimes called the "well-knownport".To the extent possible, these same port assignments are used with theUDP [46,104].The assigned ports use a small portion of the possible port numbers.For many years the assigned ports were in the range 0-255. Recently,the range for assigned ports managed by the IANA has been expanded tothe range 0-1023.Port Assignments: Keyword Decimal Description References ------- ------- ----------- ---------- 0/tcp Reserved [JBP] 0/udp Reserved [JBP] tcpmux 1/tcp TCP Port Service Multiplexer [MKL] tcpmux 1/udp TCP Port Service Multiplexer [MKL] compressnet 2/tcp Management Utility [BV15] compressnet 2/udp Management Utility [BV15] compressnet 3/tcp Compression Process [BV15] compressnet 3/udp Compression Process [BV15] 4/tcp Unassigned [JBP] 4/udp Unassigned [JBP] rje 5/tcp Remote Job Entry [12,JBP] rje 5/udp Remote Job Entry [12,JBP] 6/tcp Unassigned [JBP] 6/udp Unassigned [JBP] echo 7/tcp Echo [95,JBP] echo 7/udp Echo [95,JBP] 8/tcp Unassigned [JBP] 8/udp Unassigned [JBP] discard 9/tcp Discard [94,JBP] discard 9/udp Discard [94,JBP] 10/tcp Unassigned [JBP] 10/udp Unassigned [JBP] systat 11/tcp Active Users [89,JBP]Reynolds & Postel [Page 9]RFC 1340 Assigned Numbers July 1992 systat 11/udp Active Users [89,JBP] 12/tcp Unassigned [JBP] 12/udp Unassigned [JBP] daytime 13/tcp Daytime [93,JBP] daytime 13/udp Daytime [93,JBP] 14/tcp Unassigned [JBP] 14/udp Unassigned [JBP] 15/tcp Unassigned [was netstat] [JBP] 15/udp Unassigned [JBP] 16/tcp Unassigned [JBP] 16/udp Unassigned [JBP] qotd 17/tcp Quote of the Day [100,JBP] qotd 17/udp Quote of the Day [100,JBP] msp 18/tcp Message Send Protocol [RXN] msp 18/udp Message Send Protocol [RXN] chargen 19/tcp Character Generator [92,JBP] chargen 19/udp Character Generator [92,JBP] ftp-data 20/tcp File Transfer [Default Data] [96,JBP] ftp-data 20/udp File Transfer [Default Data] [96,JBP] ftp 21/tcp File Transfer [Control] [96,JBP] ftp 21/udp File Transfer [Control] [96,JBP] 22/tcp Unassigned [JBP] 22/udp Unassigned [JBP] telnet 23/tcp Telnet [112,JBP] telnet 23/udp Telnet [112,JBP] 24/tcp any private mail system [RA11] 24/udp any private mail system [RA11] smtp 25/tcp Simple Mail Transfer [102,JBP] smtp 25/udp Simple Mail Transfer [102,JBP] 26/tcp Unassigned [JBP] 26/udp Unassigned [JBP] nsw-fe 27/tcp NSW User System FE [24,RHT] nsw-fe 27/udp NSW User System FE [24,RHT] 28/tcp Unassigned [JBP] 28/udp Unassigned [JBP] msg-icp 29/tcp MSG ICP [85,RHT] msg-icp 29/udp MSG ICP [85,RHT] 30/tcp Unassigned [JBP] 30/udp Unassigned [JBP] msg-auth 31/tcp MSG Authentication [85,RHT] msg-auth 31/udp MSG Authentication [85,RHT] 32/tcp Unassigned [JBP] 32/udp Unassigned [JBP] dsp 33/tcp Display Support Protocol [EXC] dsp 33/udp Display Support Protocol [EXC] 34/tcp Unassigned [JBP] 34/udp Unassigned [JBP] 35/tcp any private printer server [JBP]Reynolds & Postel [Page 10]RFC 1340 Assigned Numbers July 1992 35/udp any private printer server [JBP] 36/tcp Unassigned [JBP] 36/udp Unassigned [JBP] time 37/tcp Time [108,JBP] time 37/udp Time [108,JBP] 38/tcp Unassigned [JBP] 38/udp Unassigned [JBP] rlp 39/tcp Resource Location Protocol [MA] rlp 39/udp Resource Location Protocol [MA] 40/tcp Unassigned [JBP] 40/udp Unassigned [JBP] graphics 41/tcp Graphics [129,JBP] graphics 41/udp Graphics [129,JBP] nameserver 42/tcp Host Name Server [99,JBP] nameserver 42/udp Host Name Server [99,JBP] nicname 43/tcp Who Is [55,ANM2] nicname 43/udp Who Is [55,ANM2] mpm-flags 44/tcp MPM FLAGS Protocol [JBP] mpm-flags 44/udp MPM FLAGS Protocol [JBP] mpm 45/tcp Message Processing Module [recv] [98,JBP] mpm 45/udp Message Processing Module [recv] [98,JBP] mpm-snd 46/tcp MPM [default send] [98,JBP] mpm-snd 46/udp MPM [default send] [98,JBP] ni-ftp 47/tcp NI FTP [134,SK8] ni-ftp 47/udp NI FTP [134,SK8] 48/tcp Unassigned [JBP] 48/udp Unassigned [JBP] login 49/tcp Login Host Protocol [PHD1] login 49/udp Login Host Protocol [PHD1] re-mail-ck 50/tcp Remote Mail Checking Protocol [171,SXD1] re-mail-ck 50/udp Remote Mail Checking Protocol [171,SXD1] la-maint 51/tcp IMP Logical Address Maintenance [76,AGM] la-maint 51/udp IMP Logical Address Maintenance [76,AGM] xns-time 52/tcp XNS Time Protocol [SXA] xns-time 52/udp XNS Time Protocol [SXA] domain 53/tcp Domain Name Server [81,95,PM1] domain 53/udp Domain Name Server [81,95,PM1] xns-ch 54/tcp XNS Clearinghouse [SXA] xns-ch 54/udp XNS Clearinghouse [SXA] isi-gl 55/tcp ISI Graphics Language [7,RB9] isi-gl 55/udp ISI Graphics Language [7,RB9] xns-auth 56/tcp XNS Authentication [SXA] xns-auth 56/udp XNS Authentication [SXA] 57/tcp any private terminal access [JBP] 57/udp any private terminal access [JBP] xns-mail 58/tcp XNS Mail [SXA] xns-mail 58/udp XNS Mail [SXA] 59/tcp any private file service [JBP]Reynolds & Postel [Page 11]RFC 1340 Assigned Numbers July 1992 59/udp any private file service [JBP] 60/tcp Unassigned [JBP] 60/udp Unassigned [JBP] ni-mail 61/tcp NI MAIL [5,SK8] ni-mail 61/udp NI MAIL [5,SK8] acas 62/tcp ACA Services [EXW] acas 62/udp ACA Services [EXW] via-ftp 63/tcp VIA Systems -
