"localhost" mapping to loopback ip address 127.0.0.1 http://en.wikipedia.org/wiki/Localhost special-use domain names (including localhost) http://tools.ietf.org/html/rfc6761 special-use ipv4 addresses (including 127.0.0.1) http://tools.ietf.org/html/rfc5735 127.0.0.1 convention appears in this older rfc (requirements standard) http://tools.ietf.org/html/rfc1122 have 127.0.0.1 reserved going back to rfc790 (sep1981) http://tools.ietf.org/html/rfc790 trivia at interop '88 ... some past posts http://www.garlic.com/~lynn/subnetwork.html#interop88 sunday night and early monday morning the floor nets were constantly crashing with packet storms ... fortunately fix was found before the show starts. work-around/convention specification then appears in rfc1122 (even tho I was still at ibm, i had equipment in another vendor's booth at the show). other trivia, the former RFC editor (Postel) would let me help him with (periodically released/updated) STD1 (before he passed). my rfc index http://www.garlic.com/~lynn/rfcietff.htm I even got con'ed into giving electronic commerce seminar to USC/ISI and USC comp.sci graduate deprt. I even covered some amount of the first patent (well before it was granted) in this patent portfolio http://www.garlic.com/~lynn/aadssummary.htm as I've commented a number of times, original mainframe tcp/ip product was implemented in vs/pascal ... which had none of the exploit & buffer overflow problems that are epidemic in tcp/ip stacks implemented in C language. Originally, it did have some performance issues (getting about 44kbytes/sec using 3090 processor) but I did the changes to support RFC1044 and in some tuning tests at cray research between 4341 and cray ... got sustained 4341 channel throughput using only modest amount of 4341 processor (possibly 500 times improvment in number of bytes moved per instruction executed) http://www.garlic.com/~lynn/subnetwork.html#1044 -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
