Hi!
Does anyone know if there is any imperative (writen or oral) to avoid registering 2 letter second level domains?
No, there isn't. There are lot of 2 letter second level domains under almost all TDL, e.g. es.net bt.com <2-letter-US-state-code>.us uc.edu co.uk ac.uk co.at ac.at .... In Germany we are just considering to install 2-letter-state-codes as second level domains to cope with the steady increase of domains.
I know some top level domains refuse to do so based on possible conflicts (due to user misconfigurations) with current or future top level domains, but others allow it.
We have a request to register one of these under "es" and I want some advice before saying "yes" or "no".
Thanks,
Miguel
