It allows the program to run pretty much at full speed, and then reports memory leaks. -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug

Re: [GLLUG] moving a fixed ip number
I do believe that DNS was invented to solve this problem, inter alia :) MeJ On 04/02/2020 12:54, John Winters via GLLUG wrote: On 04/02/2020 11:09, Oliver Howe wrote: It is a leased line into my office.

If you move to a new provider, then almost certainly not - unless you move to the provider for whom your current one is a reseller. Your IP address will be one of a range belonging to and routed to your underlying supplier. You can't port them like mobile phone numbers.

According to whois the owner is mdnx so I will try them and see if they can help. If you don't own the IP range (i.e. it's _at least_ a /24 PI allocated to you by RIPE), it's very very unlikely your current ISP will let you take it with you. -- GLLUG mailing list GLLUG@mailman.lug.org.uk https://mailman.lug.org.uk/mailman/listinfo/gllug

Assuming you mean your IP address, that would depend on who your ISP is and whether it is genuinely fixed (rather than just having happened to stay the same for a long time). With a genuinely fixed address, and assuming you keep the same ISP, I would expect it to be possible, but you really need to ask them. If you change ISP, then definitely not.

Long answer: It will really depend on your ISP. If you are keeping the same ISP, then this should not be an issue. However, I would recommend you contact them before moving to ensure continuity of service (including your static IP!) Cheers!
