Not encountering a problem for "a number of years" does not mean
you're not going to have problems in the future. I know a lot of
people who don't backup their data, some who justify it by asserting
that they've not had a problem so far.

Maintaining identical development, staging and live environments is
one of the key components of reliable, repeatable and streamlined
development, testing and deployment, but if you're happy with what
you've got then by all means continue as before. I was just offering a
best practice suggestion that would solve your current problem and
likely some you'll encounter in the future.

No it wouldn't. If you care to read exactly what I wrote, you put the
development site under mysite.local rather than mysite.com. It won't
mask or hide the live site and it won't have any negative impact when
you put it live unless you've used the domain name in links.

Most DHCP servers can reserve an IP address for a specific MAC address
such that that IP always gets given to that NIC.

That's completely up to you, I'm just trying to help.

I'm not annoyed, I'm mildly frustrated. You did not respond to my
initial suggestion in the other thread but continued to discuss the
problem with others. I apologise if my tone came across as annoyed,
but it's polite to respond to others when they communicate with you.

Good day to you sir ;-)
