; Nameserver info for FIDONET.ORG domain ; ; ------------------------------------------------------------------- ; ; A copy of the DNS file is always available via: ; From the Internet: ; ftp://ftp.fidonet.org/pub/fidonet/info/fidonet.dns ; ; From FidoNet: ; FidoNet File-Request: ; from 1:13/10 for magic-name DNS -or- ; target an Update-Request for FIDONET.DNS ; ; ------------------------------------------------------------------- ; ; How to Read the information in the DNS File: ; ------------------------------------------- ; ; The leftmost column contains either the SITENAME or the wildcard ; pattern for the Net. ; ; The 2nd column is *always* "IN". ; ; The 3rd column contains either: ; NS = Nameserver Record ; in which case it is followed by the ; Fully-Qualified-Domain-Name of the IP machine ; which is delegated "Authority" for the subdomain ; named in Column 1. ; A = Address Record ; followed by the "dotted quad" IP address of the ; hostname referred to in Column 1. ; CNAME = "Canonical Name" ; followed by the FQDN of the *real* name of the ; machine being referred to. It tells the DNS what to ; lookup and substitute. ; MX = Mail Exchanger ; followed by a precedence number and the name of ; the machine where this host's mail should be sent. ; This indicates the IP-connected machine that MAIL is ; to be sent to which the gateway named in column 1 ; is connected to, or which *does* know how to get ; Mail to the gateway/host named in column 1. ; This *must* be the *real* name of the machine (the ; one which it's SMTP-daemon answers as) and cannot ; point to a CNAME record. ; There may be multiple MX records, in which case they ; are tried in order of precedence. The MX-records ; also tell the higher numbered MX-receivers that ; they are to forward the mail ONLY to the lower numbered ; MX-receivers, and NOT to try to "talk to itself". ; The real entries for the MX-receivers *must* have ; an 'A' record and cannot point to a hostname which ; itself is only referred to with MX-records. ; ; Comments: ; Everything following a semi-colon is a comment. ; For the gateway SITEnames, the FidoNet Node Number of the ; gateway host is usually behind a semi-colon (it is for ; information only and is NOT part of the DNS mechanism). ; For the wildcard MX-records for the Nets, I usually have ; the SITEname of the gateway which the MX-receiver forwards ; to behind the semi-colon. ; ; ; ================================================================ ; ; Each Net which has a gateway has a wildcard MX-record. ; The IP site which the mail is directed to is expected to have ; installed the sendmail or smail rules necessary to queue ; ALL mail for *.nNET.z#.fidonet.org for pickup by the ; appropriate gateway site. ; ; A wildcard MX-record is maintained for each Zone, so that ; there is always a "default" gateway for any new Nets which ; are placed in the Nodelist by the *C's. ; ; At present, the Zone-1 "default" MX points to fidonet.fidonet.org, ; which queues mail for gating by 1:1/31. ; This catches all addresses in Zone-1 which do NOT otherwise ; have an MX-record for the Node or Net. ; ; IT IS HIGHLY LIKELY THAT ZONE-1 WILL CEASE TO HAVE A "DEFAULT" ; GATEWAY IN THE VERY NEAR FUTURE. THERE IS NO WAY THIS SITE CAN ; HANDLE THE AMOUNT OF TRAFFIC COMING THRU FOR ZONE-1 AT THE ; CURRENT LEVELS. ; ; Where possible, the gateway sitename is shown as a Comment ; behind a semi-colon after the MX-record. ; ; ======================== EOF =================================
