How dynamic is dynamic


[link to this post]
 
I'm wondering how dynamic are the BT home broadband IP addresses these days ?

Reason is that someone I support is using their home broadband to connect with (Windows) Remote Desktop into their work PC.
Every morning the last few days I've had to login remotely to the work PC to whitelist their new IP in the firewall.
Don't know whether this is an FTTC or an ADSL version connection.

They might be turning off their router overnight, as daily is unusual but not unheard of.

This is where you really need a VPN to the firewall, rather than white listing, there are enough problems in the RDP protocol, you need to wrap it in something more secure.

Plus of course I hope when white-listing he removes the previous address for that user from it. An easily forgotten step.

My broadband basic info/help site - www.robertos.me.uk. Domains, site and mail hosting - Tsohost.
Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.

Thanks both.

Very good point Robertos.

JChamier : I doubt the router is being turned off overnight, although I know the laptop definitely was being turned off.
The VPN is a very good point. It had occurred to me, but haven't done anything about that. Yet. It can go on today's ToDo list smile

I have had a dynamic IP for Months but that's using our own router and not BT's one and the only time our IP has changed in less than a month is when I have done changes to our router.

But the last time I was using BT's Hubs I was seeing it last at least a month before it did its remote reboot.

FTTC connection here will give a new IP after every dropout or reboot, so very dynamic.

That rather depends on how often you suffer a dropout or reboot. Here that's perhaps once a month, so dynamic yes but only changing around once a month.

Agreed, I have also rebooted our router and when it connected back up was given the same IP.

I've currently got DLM dropping my line every night working my way from 6db to 3db SNR and I have kept the same IP every resync.

That's on EE with a dynamic IP.

It all depends what IP's ISP's have available in their pools.

I had FTTC via NowTV installed on the 11th March and according to the router at least it's not dropped as showing 512 hours uptime for WAN. I have also seen the SNR change, and the sync speed go up multiple times.
