Er, no, the double quotes will mean that the backtick command is
expanded at the time the alias is defined rather than at the time it
is run. So you'll get the ifconfig output from the time the shell
started, always.
You want
alias checketh0 'echo `ifconfig eth0 | grep "inet addr:" |awk
'\''{print $2}'\'' | cut -c 6-`'
