Lightbulb Tld.subdomain.name.subname

Way back in the early dawn of the 'net, there were two competing notations for specifying a FQDN, the familiar name.subdomain.domain.tld (such as news.bbc.co.uk) and the reversed tld.domain.subdomain.name (uk.co.bbc.news). And if memory serves, only the UK used the latter style of FQDN for a period of time. Nowadays, the reversed FQDN is used by JAVA and ANDROID for classes.

Does anyone have an reference material that explains why the standard notation was chosen? One would think it would have been easier to parse a FQDN of the form tld.domain.subdomain.name; but then it may have been easier to discuss appending domains when resolving names.

And as a totally hypothetical exercise, if you had complete control - how would you redesign FQDNs?

radsqlrelay - relay SQL queries to a central database server SYNOPSIS
radsqlrelay [-?] [-d sql_driver] [-b database] [-f file] [-h host] [-u user] [-P port] [-p password] [-1] [-x] file_path DESCRIPTION
radsqlrelay tails a SQL logfile and forwards the queries to a database server. Used to replicate accounting records to one (central) data- base, even if the database has extended downtime. The SQL logfile is created by the rlm_sql_log module. The module must be configured in the radiusd server before you can use radsqlrelay. OPTIONS

Print usage help information. -d sql_driver Driver to use: mysql, pg, oracle. -b database Name of the database to use. -f file Read password from file, instead of command line. -h host Connect to host. -u user User for login. -P port Port number to use for connection. -p password Password to use when connecting to server. -1 One-shot mode: push the file to database and exit. -x Turn on debugging. file_path The pathname of the SQL logfile to use. NOTES
Oracle driver The command "radsqlrelay -d oracle -b db.domain.tld sql-relay" reads the database description stored in $TNS_ADMIN/tnsnames.ora: db.domain.tld = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = db.domain.tld)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = <DB SID>) ) ) SEE ALSO
