DOMAINSFILE mydomains.tabNormally you don't need this command, because if there is a domains file in your language, it should be selected automatically. But the DOMAINSFILE command can be useful if you want to use a domains file in a new language, for example. If the name of the file doesn't include a directory, it will be looked for wherever analog normally expects to find its language files.
You should have got a domains file with the program, but if you've lost it, you can download one from http://www.analog.cx/ukdom.tab. It should contain on each line a domain code, followed by a number, followed by its location, like this:
ad 2 Andorra ae 3 United Arab Emirates [...]It does not need to be in alphabetical order, though humans may prefer it that way. Subdomains do not go in the domains file: you can list them in the Domain Report using the SUBDOMAIN command.
There are some problems with this. A few countries have organisations at both levels 2 and 3 (for example asaspace.at and univie.ac.at). In those cases I've favoured false negatives over false positives by using the bigger number. (Also there is a correction which will make most of them right again: the first component is always removed from a hostname of three or more components.) For other countries, I don't have enough information to tell what the level should be. I've just given those a 1. Do let me know if you have any more information, or corrections, for the numbers.
For numerical addresses, the organisation is considered to be at level 2 if the first component is 24, 61-68, 80-81 or 128-255; and otherwise at level 1. Again this is only an approximation -- for example, many organisations use two adjacent blocks of numbers, or subdivided blocks -- but it's the best we can do without looking up every address we come across. (Note that you can always see more detail using the SUBORG command).
Lines starting with a hash (#) in the domains file are considered to be comments.
