Netvigator - "locking" IP possible?

Hi

If an alway-on computer (directly or through a router) continues using the same Netvigator IP address 24/7, is it likely that the IP can be effectively "locked" (ie, never changes), until there is a serious, prolonged internet network outage?

Thanks in advance for any feedback!

It still depends on the ISP's policy.

You can not reserve your IP address merely by keeping the connection up if your ISP provides another address to you in the next time period.

E.g. when I used HKBN, effectively I got the same IP address for the same MAC address.
But 3HK would switch my IP address at times even if I had my router always up.

Netvigator 個DHCP server本身好少主動改派叧一個IP比你如果你個router同gpon長開. 有時想轉個IP要關router同gpon幾分鐘先派個新IP.

為安全計,
唔係每次boot bb modem去換IP會好d咩!
e.g.用eBanking前後,
點解係都要用fix IP咁危險,
(e+有好多硬件商都起個server去解決無fix IP o既問題,
當然監守自盜又係另一回事>商譽同追究都係有一定阻嚇力,
e.g.8達通事件).

    根本純粹上網﹐只係睇網頁係有無fix ip都無問題。

要fix ip﹐好明顯係想經常在街外入番屋啦。
一係用DDNS﹐不停自己upload自己個IP 去DDNS Server﹐其實以你的安全問題來講﹐都係無分別﹐都係你所講的危險。

無錯,
但分別在於,
fix IP係打開度門比人scan自己掟過d乜出街(只要mon住個fix IP就得),
但每次轉IP無咁易比人mon實,
如經硬件生產商server做高風險野(e.g.IP cam or Home NAS),
只有硬件生產商可mon實你去過邊同掟過d乜出街(e.g.password),
如大量有人被硬件生產商偷野,
就有一定渠道進查(e.g.小米野upload門事件一定有人爆料).

    冇分別,scan你掟過乜野出街係physically條線掟過乜野出街,同IP本身無關。

+1
NAS之類, connect翻官方server都係跟機身serial number (Synology個DDNS已經係好例子)
就算IP變, ISP變, 地方變, 都一樣認得出同一部機

有能力跟到你條線 i.e. Mac address
理論上應該淨係得 ISP 做到,係咪?
